Electric knife sharpeners vary most in the angles they support, how much control they offer, and whether they can handle more than kitchen knives. My best overall pick is the Chef’sChoice 15XV EdgeSelect for its dedicated 15-degree sharpening approach; the Work Sharp MK2 stands out for sharpening both knives and tools, while the Presto 08810 EverSharp offers a simpler three-stage setup. The main tradeoff is between guided convenience and versatility: a kitchen-focused machine can be easier to use, while a multipurpose model may demand more care. Sharpening stages alone do not tell the whole story, since angle compatibility and the kinds of blades you own matter just as much. Read on for the full comparison and advice on choosing among these 15 electric knife sharpeners.

Key Takeaways
- Chef’sChoice 15XV EdgeSelect leads the kitchen-focused options for shoppers prioritizing a dedicated 15-degree edge; it is less flexible than models that support both 15- and 20-degree knives.
- Chef’sChoice 1520 and AngleSelect stand apart for supporting both 15- and 20-degree knives, making them more adaptable to mixed knife collections than single-angle choices.
- Work Sharp MK2 is the most distinct multipurpose pick because its knife-and-tool focus serves needs beyond ordinary kitchen sharpening; that broader use comes with a different learning curve than guided kitchen machines.
- Presto 08810 and Presto 08800 offer straightforward EverSharp options, while stage count alone should not decide between them or other compact kitchen sharpeners.
- Scissors slots and 5-in-1 claims make the Narcissus and KAZRBEP options relevant for buyers seeking extra functions, but shoppers should prioritize fit with their knives before added versatility.

More Details on Our Top Picks
TER 3-Stage Electric Knife Sharpener, Silver
The TER earns my everyday-kitchen pick by combining three diamond-abrasive stages with a fixed 20° sharpening angle: the stages handle edge restoration, honing, and polishing without asking the user to choose a separate system. Its magnetic debris collector and non-slip feet also address two practical annoyances—metal dust and movement on the counter. Compared with the Dawnstar S858, it adds a third stage and a stated serrated-knife polishing slot, while staying compact at just over 10 inches long. The tradeoff is that the 20° angle is aimed at standard household edges, not knives designed for a different bevel. Serrated blades belong only in the polishing slot, so this is less flexible than the Work Sharp MK2 for varied tools and blade types.
Pros:- Three stages cover edge restoration, honing, and polishing.
- Diamond abrasives are specified for the sharpening system.
- Magnetic collector helps contain metal debris.
- Non-slip feet support steadier countertop use.
Cons:- Fixed 20° angle may not match knives designed for a different bevel.
- Serrated knives should use only the polishing stage.
- More kitchen-focused than multi-tool options such as the Work Sharp MK2.
Best for: Home cooks who want a staged sharpener for standard straight-edge kitchen knives and occasional serrated-knife polishing.
Not ideal for: Owners of Japanese or other knives with a sharpening angle unlike 20°, and anyone seeking one sharpener for axes, scissors, or outdoor tools.
- Stages:3
- Abrasive:Diamond
- Sharpening angle:20°
- Dimensions:10.43 × 4.13 × 3.74 in
- Color:Silver
- Included components:Electric sharpener, magnetic dust collector, user manual
- Warranty and service:12-month replacement or refund policy; 12-month after-sales service
Our verdict“Choose the TER for a compact, three-stage routine on standard household knives, but skip it if your collection needs a different angle or broader tool support.”
Work Sharp MK2 Electric Knife and Tool Sharpener
The Work Sharp MK2 is the lineup’s broadest-use option: its flexible abrasive belts can work across kitchen and pocket knives, serrated blades, scissors, axes, and garden tools. That range makes it a different kind of purchase from the TER 3-Stage, which is built around a fixed angle and kitchen-knife stages. The MK2’s two-speed motor gives users a lower-control setting and a faster option for heavier sharpening tasks, while the edge guide helps support blade positioning. The tradeoff is a belt-based system rather than the simple staged slots found on the TER or Dawnstar S858; users also need replacement belts over time. Its plastic construction is functional but less substantial than a heavier bench-style machine, so this pick suits practical versatility over a dedicated kitchen-counter setup.
Pros:- Flexible belts cover a wide range of knife and tool types.
- Two motor speeds provide more control across light and heavier tasks.
- Includes an edge guide for blade positioning.
- Three-year warranty is longer than the 12-month policies listed for several kitchen-focused picks.
Cons:- Abrasive belts are consumable and require replacement.
- Plastic construction may feel less substantial than a dedicated bench sharpener.
- Its versatility may be unnecessary for buyers sharpening only standard kitchen knives.
Best for: Households with kitchen knives plus pocket knives, scissors, axes, or garden tools that need one adaptable powered sharpener.
Not ideal for: Cooks who want a simple, fixed-slot kitchen sharpener or do not want to manage abrasive belt replacement.
- Model:WSKTS2
- Type:Electric knife and tool sharpener
- Motor:Two speed
- Included components:Abrasive belts, knife sharpener
- Material:Plastic
- Dimensions:7.02 × 2.26 × 1.27 in
- Warranty:3 years
Our verdict“Pick the MK2 if you want one powered system for kitchen knives and outdoor tools; choose the TER or Dawnstar for a simpler kitchen-only routine.”
Northmas Electric Knife Sharpener, 2-Stage, 100–240V, Blue
Northmas is the most compact, straightforward choice here for buyers who want a small two-stage machine rather than a larger multi-stage setup. Its coarse and fine slots divide sharpening from polishing, and the 7.8-inch length makes it easier to store than the TER 3-Stage or Dawnstar S858. Support for 100–240V and an included adapter also make it more adaptable for use with compatible outlets when traveling. That portability comes with limits: the listing gives no abrasive material or sharpening angle, so buyers have less information for matching it to particular knives than they do with the TER’s diamond abrasives and fixed 20° angle. The instructions also call for holding the blade against the slot wall, a technique that may take practice. It is a compact home-use option, not a stated multi-tool sharpener.
Pros:- Compact 7.8-inch length is easier to store than the TER and Dawnstar.
- Separate coarse and fine stages divide sharpening and polishing.
- 100–240V compatibility supports use across a broad voltage range.
- Adapter is included.
Cons:- Product data does not specify the abrasive material or sharpening angle.
- Instructions require positioning the blade against the slot wall.
- Requires an electrical outlet and is not described as a multi-tool sharpener.
Best for: Apartment cooks and travelers who need a small two-stage sharpener with broad voltage compatibility for standard home knives.
Not ideal for: Buyers who need a specified sharpening angle, documented abrasive type, or support for scissors and outdoor tools.
- Stages:2: coarse sharpening and fine polishing
- Voltage:100–240V
- Dimensions:7.8 × 2.1 × 3.1 in
- Weight:1.2 lb
- Material:Plastic
- Color:Blue
- Included components:Adapter, main body
- Warranty and service:12-month replacement or refund service; 24-month after-sales service
Our verdict“Choose Northmas when compact storage and voltage flexibility matter more than a specified angle or a wider range of sharpening tasks.”
Dawnstar Electric Knife Sharpener with Two Sharpening Stages
The Dawnstar S858 is aimed squarely at cooks sharpening straight-edge kitchen knives, including chef’s, slicing, and santoku styles. Its coarse and fine stages provide the basic sharpen-and-polish sequence, while magnetic dust collection boxes help manage the debris produced during use. Compared with the Northmas 2-Stage, Dawnstar is larger but names more kitchen-knife types and specifies its collection system; compared with the TER 3-Stage, it gives up a third stage and a serrated-knife polishing slot. The stated 100–240V compatibility adds flexibility, but the manufacturer notes that the first sharpening may take longer to shape the blade angle. It is also not presented as a tool sharpener, so buyers with scissors or outdoor blades should look at the Work Sharp MK2 instead.
Pros:- Coarse and fine stages handle sharpening and polishing.
- Specifically suited to chef’s, slicing, and santoku knives.
- Magnetic collection boxes help simplify metal-dust cleanup.
- 100–240V compatibility.
Cons:- Designed for kitchen knives and may not suit other blade types.
- First sharpening may take longer to establish the blade angle.
- Lacks the third stage and serrated polishing slot specified for the TER.
Best for: Home cooks who mainly sharpen straight-edge chef’s, slicing, and santoku knives and want magnetic debris collection.
Not ideal for: Owners of serrated knives, scissors, axes, or other tools who need those blades covered by the same sharpener.
- Model:S858
- Sharpening stages:2: coarse and fine
- Voltage compatibility:100–240V
- Dimensions:9.4 × 4 × 5.5 in
- Weight:1.4 lb
- Material:Plastic
- Color:Silver Gray
- Warranty and service:12-month replacement or refund policy; extended 12-month after-sales service
Our verdict“Choose Dawnstar for routine sharpening of straight-edge kitchen knives with debris collection, but look elsewhere for serrated blades or tools.”
Narcissus S809 3-Stage Electric Knife Sharpener
The Narcissus S809 stands apart for listing compatibility with straight, serrated, stainless steel, and ceramic knives, plus an open port for scissors and axes. Its three diamond-abrasive stages repair, hone, and polish, giving it a broader stated blade mix than the kitchen-focused Dawnstar S858 and the compact two-stage Northmas. A removable bottom box collects metal dust, and the fixed 20° angle offers a consistent setup for knives designed around that bevel. That fixed angle is also the main limitation: it may not fit blades sharpened to another angle, so the wider compatibility list does not make it universal. The manual recommendation is worth following before use, particularly given the different blade types. For buyers with only standard straight-edge knives, the TER offers a similar three-stage format with a clearly defined kitchen focus.
Pros:- Three diamond-abrasive stages repair, hone, and polish.
- Listed for straight, serrated, stainless steel, and ceramic knives.
- Open port adds support for scissors and axes.
- Removable bottom box collects metal dust.
Cons:- Fixed 20° angle may not suit knives designed for a different bevel.
- Instructions recommend reading the manual before first use.
- Broader blade compatibility requires more care in choosing the correct use and stage.
Best for: Households with a mix of straight and serrated knives, ceramic blades, and occasional scissors or axes that match the fixed 20° setup.
Not ideal for: Owners of knives designed for a different sharpening angle, or cooks who want a simpler machine limited to standard kitchen blades.
- Model:S809
- Sharpening stages:3
- Abrasive material:Diamond
- Sharpening angle:20°
- Compatible blades:Straight, serrated, stainless steel, and ceramic knives
- Additional tool sharpening:Scissors and axes
- Voltage:100–240 V
- Continuous operation:Over 1 hour
- Warranty and support:12-month replacement or refund policy; 24-month technical assistance
Our verdict“Pick the S809 for a varied collection of blades and tools when 20° suits your knives, but choose a different system if your edges need another angle.”
Hrevzon 3-Stage Electric Knife Sharpener with Diamond Abrasives
The Hrevzon TG2101 is a flexible pick for households with more than standard straight-edge kitchen knives. Its coarse, fine, and polishing stages pair with diamond abrasives to cover edge repair through finishing, while its stated compatibility with serrated and ceramic knives gives it broader range than the straight-blade-focused Narcissus QN-M866. A magnetic, detachable shavings collector and four non-slip feet address two practical parts of the job: cleanup and steadiness on the counter.
The tradeoff is pace and technique. This pull-through design calls for repeated backward strokes, and a badly dulled blade may take around a minute to sharpen. Buyers wanting a compact, simpler two-stage option for straight knives and scissors may prefer the Narcissus; I’d choose the Hrevzon when knife variety matters more than quick, minimal-step sharpening.
Pros:- Three stages cover coarse sharpening, edge refinement, and polishing.
- Stated compatibility includes straight-edge, serrated, and ceramic knives.
- Four non-slip feet support steadier use on a countertop.
- Detachable magnetic collector makes metal-shaving cleanup easier.
Cons:- Pull-through sharpening requires drawing the blade backward several times.
- Heavily dulled blades may need around a minute of sharpening.
- The listed included components contain only the sharpener.
Best for: Home cooks who maintain a mix of straight-edge, serrated, stainless steel, and ceramic kitchen knives and want a dedicated polishing stage.
Not ideal for: Anyone who wants a quick touch-up with minimal repeated passes, or mainly needs to sharpen scissors.
- Model:TG2101
- Sharpening stages:3: coarse, fine, and polish
- Abrasive:Industrial-grade diamond
- Compatible knives:Straight-edge, serrated, stainless steel, and ceramic
- Base:Four non-slip silicone feet
- Shavings collector:Detachable magnetic collection box
- Dimensions:12.2 × 4.9 × 4.6 in
- Material and color:Metal; black and orange
Our verdict“Choose the Hrevzon if your household knives span several blade types and you’re comfortable making repeated passes for a three-stage finish.”
Presto 08810 Professional EverSharp Electric Knife Sharpener
The Presto 08810 stands out for buyers who want one electric sharpener for kitchen knives and sport blades. Its three-stage system uses blade guides and a thickness selector, so it can accommodate a wider range of blade thicknesses than the Hrevzon TG2101, which is described around household knife types rather than a thickness selector. Presto also lists kitchen, hunting, fillet, and Santoku knives as compatible, making it the more purpose-built choice for mixed kitchen-and-outdoor use.
That range comes with a storage tradeoff: at 18.43 inches long, it needs more shelf or counter space than the compact Narcissus QN-M866. Suction-cup feet help hold it steady, but the 120 V, 60 Hz power specification limits where it can be used. I’d favor it over a kitchen-only model when sport knives matter; buyers with limited storage or 100–240 V needs should look elsewhere.
Pros:- Three stages provide light, medium, and fine sharpening.
- Adjustable guides accommodate different blade thicknesses.
- Listed for kitchen and sport knives, including hunting and fillet knives.
- Suction-cup feet help stabilize the unit during sharpening.
Cons:- Its 18.43-inch listed length may make storage difficult in small kitchens.
- The 120 V, 60 Hz power specification limits electrical compatibility.
- The plastic construction may feel less substantial than a metal-bodied option.
Best for: Home cooks and outdoor enthusiasts who want a guided electric sharpener for kitchen, hunting, fillet, and Santoku knives.
Not ideal for: People with compact kitchens or users who need a sharpener compatible with power supplies other than 120 V, 60 Hz.
- Model:08810
- Sharpening stages:3
- Grit types:Light, medium, and fine
- Compatible knives:Kitchen, hunting, fillet, and Santoku
- Abrasive wheels:Sapphirite
- Power:120 V, 60 Hz
- Dimensions:18.43 × 11.25 × 2.18 in
- Weight and warranty:5.1 lb; 1-year limited warranty
Our verdict“Pick the Presto if you need guided sharpening for both kitchen and sport knives and have room to store its longer body.”
Narcissus 2-Stage Electric Knife Sharpener with Scissors Slot
The Narcissus QN-M866 is the compact choice for kitchens where a sharpener needs to earn its storage space. At 8.6 × 2.6 × 2.9 inches and 1.6 pounds, it is much smaller than the Presto 08810, whose longer body is better suited to buyers with room for a dedicated appliance. The Narcissus keeps the routine straightforward with coarse and fine stages, and its side slot adds a practical extra for scissors—something the Hrevzon TG2101’s listed features don’t provide.
The narrower scope matters: this model is designed for straight-blade knives, unlike the Hrevzon’s stated serrated and ceramic compatibility. Its 30-watt motor and magnetic collection box suit everyday sharpening and tidier cleanup, but first-time users should follow the manual and product video before operating it. I’d choose it for compact kitchens and scissor owners, not for a collection with serrated blades.
Pros:- Compact, lightweight body is easier to store than the Presto 08810.
- Coarse and fine stages handle sharpening and polishing.
- Side slot provides a way to sharpen scissors.
- Magnetic metal-dust collection box supports easier cleanup.
Cons:- Designed for straight-blade knives rather than a broad range of blade types.
- Instructions recommend watching the product video and reading the manual before first use.
- Two stages provide less sharpening-stage control than three-stage models such as the Hrevzon TG2101.
Best for: Apartment cooks and small-household owners who sharpen straight-edge kitchen knives and want a dedicated slot for scissors.
Not ideal for: People maintaining serrated or ceramic knives, or buyers who prefer a model that needs little setup guidance.
- Model:QN-M866
- Sharpening stages:2: coarse and fine
- Motor power:30 W
- Input voltage:100–240 V
- Abrasive material:Carborundum
- Dimensions:8.6 × 2.6 × 2.9 in
- Weight:1.6 lb
- Warranty and service:12-month replacement or refund policy; extended 24-month after-sales service
Our verdict“Choose the Narcissus if storage space is tight and you want one compact unit for straight knives and scissors.”
KAZRBEP 5-in-1 Electric Knife Sharpener with Scissor Sharpening
The KAZRBEP 5-in-1 is the broadest-use option here for buyers who want more than a kitchen-knife sharpener. It is listed for straight and serrated knives, cleavers, ceramic knives, scissors, and axes, while the three speed settings let the user choose low, medium, or high. That makes it more versatile on paper than the Narcissus QN-M866, which focuses on straight-blade knives and scissors. Its spring-loaded angle guide and removable ceramic polishing bar add controls that simpler pull-through designs may not offer.
Versatility means more parts and more technique: sharpening takes several passes per slot, and the product listing doesn’t clarify the order of its dimensions. The Hrevzon TG2101 is a clearer fit if you mainly want a household knife sharpener with a magnetic collector; KAZRBEP makes more sense when scissors and axes also need attention. I’d skip it for buyers who want a simple, clearly specified kitchen-only appliance.
Pros:- Listed for straight and serrated knives, cleavers, ceramic knives, scissors, and axes.
- Three speed settings provide low, medium, and high operating choices.
- Spring-loaded guide helps maintain a consistent sharpening angle.
- Removable ceramic polishing bar and debris plate support finishing and cleanup.
Cons:- Several passes per slot may be needed to sharpen a blade.
- The dimension listing does not specify which measurement corresponds to length, width, or height.
- Plastic construction may be less substantial than the metal-bodied Hrevzon TG2101.
Best for: DIY-minded households with assorted blades—including cleavers, ceramic knives, scissors, and axes—that want adjustable speed and angle guidance.
Not ideal for: Cooks seeking a simple appliance for routine kitchen-knife touch-ups or buyers who want clearly documented dimensions and straightforward operation.
- Sharpening stages:3
- Speed settings:3: low, medium, and high
- Abrasive:Diamond
- Sharpening angle:20°, adjustable up to 32.5°
- Additional sharpening tool:Removable ceramic polishing bar
- Compatible tools and blades:Straight and serrated knives, cleavers, ceramic knives, scissors, and axes
- Dimensions:5.6 × 12 × 4.5 in; order unspecified
- Material and color:Plastic; light gold
Our verdict“Choose the KAZRBEP when you need one powered sharpener for a wide assortment of blades and don’t mind multiple passes.”
Chef’sChoice AngleSelect 3-Stage Electric Knife Sharpener for 15° and 20° Knives
The Chef’sChoice AngleSelect is the most specialized pick here for cooks who own knives with different factory edge angles. Its three-stage diamond system supports both 15-degree Asian-style and 20-degree European- and American-style edges, so buyers can match the sharpener to the blade rather than settle on one angle. That distinction sets it apart from the Hrevzon TG2101, whose listed specs cover several knife types but don’t identify supported edge angles. Automatic guides help position blades, while flexible stropping and polishing discs handle more than initial sharpening.
This angle-specific control comes with a more involved routine than the two-stage Narcissus QN-M866, and the unit needs a power source. Its listed compatibility includes straight-edge, serrated, single-bevel, and double-bevel blades, but it is less appealing if you want a compact, simple sharpener for ordinary straight knives. I’d choose it when preserving both 15° and 20° edges matters more than reducing steps.
Pros:- Supports both 15° and 20° knife edges.
- Diamond abrasives and flexible discs sharpen, hone, and polish.
- Listed compatibility includes straight-edge, serrated, single-bevel, and double-bevel blades.
- Automatic guides help position blades during sharpening.
Cons:- Requires an electrical power source.
- The three-stage process involves more steps than a basic two-stage sharpener such as the Narcissus QN-M866.
- Its angle-specific features may be unnecessary for buyers whose knives use only one edge angle.
Best for: Cooks with a mix of Asian-style and European- or American-style knives who want to maintain both 15° and 20° edges.
Not ideal for: Buyers who want a minimal-step sharpener for a single knife type or need a sharpening method that works without electrical power.
- Model:0115207
- Sharpening stages:3
- Abrasive:100% diamond
- Supported edge angles:15° and 20°
- Compatible blades:Straight-edge, serrated, single-bevel, and double-bevel
- Material:Diamond-coated stainless steel
- Dimensions and weight:12 × 6 × 6.4 in; 4.9 lb
- Warranty:3-year limited warranty
Our verdict“Choose the AngleSelect if you maintain both 15° and 20° knives and want guided, multi-stage sharpening for each.”
Chef’sChoice 15XV EdgeSelect 3-Stage Electric Knife Sharpener
The 15XV suits cooks who want a consistent 15-degree edge and are comfortable changing a knife’s original geometry. Its three stages use diamond abrasives to sharpen, hone, and polish, while angle guides reduce guesswork. Compared with the Chef’sChoice 1520, this model is less flexible: the 1520 supports both 15- and 20-degree edges, while the 15XV is designed to convert traditional 20-degree edges to 15 degrees. That narrower focus makes the choice clearer for buyers who want the finer edge, but less suitable for households with knives they want to keep at 20 degrees. It handles both straight and serrated blades, though the electric format and fixed edge target make it less adaptable than the Work Sharp MK2 for varied tools.
Pros:- Three stages sharpen, hone, and polish the edge
- Diamond abrasives and precision guides support consistent sharpening
- Works with straight-edge and serrated knives
- Can convert traditional 20-degree edges to a 15-degree edge
Cons:- Its 15-degree target may not suit every knife
- Requires an electrical outlet
- Less flexible than the Chef’sChoice 1520 for preserving different edge angles
Best for: Home cooks with straight-edge and serrated kitchen knives who specifically want to convert traditional 20-degree edges to 15 degrees.
Not ideal for: Owners of knives that should retain a 20-degree edge, or anyone who needs a sharpener for tools beyond kitchen knives.
- Brand:Chef’sChoice
- Model:15XV (0101500)
- Stages:3
- Abrasive:100% diamond abrasives
- Knife compatibility:Straight-edge and serrated knives
- Edge angle:15 degrees; converts traditional 20-degree edges
- Dimensions:10 × 4.25 × 4.25 inches
- Sharpening time:Approximately 1 minute for first sharpening; 10 seconds for resharpening
- Warranty:3-year limited warranty
Our verdict“Choose the 15XV if you want a guided three-stage sharpener that converts compatible knives to a 15-degree edge; choose the Chef’sChoice 1520 if you need both 15- and 20-degree options.”
Chef’sChoice 1520 3-Stage Electric Knife Sharpener for 15- and 20-Degree Straight-Edge and Serrated Knives
The Chef’sChoice 1520 is the more adaptable choice for kitchens with knives built around different edge angles. Its three-stage diamond system supports both 15- and 20-degree edges, then uses polishing disks to finish them. That distinction matters beside the 15XV: the 15XV is aimed at converting compatible 20-degree knives to 15 degrees, while the 1520 lets buyers work with either angle. It also accepts straight-edge and serrated blades, giving it broader kitchen coverage than the Presto 08800, which is not suited to most serrated knives. The tradeoff is that this versatility still comes in a countertop electric unit, and first sharpening takes about a minute. I’d favor it for a varied knife drawer, not for someone seeking a compact manual-free storage solution.
Pros:- Supports both 15- and 20-degree edges
- Sharpens straight-edge and serrated knives
- Diamond abrasives and polishing disks handle sharpening and finishing
- Precision guides help maintain a consistent angle
Cons:- Requires electricity
- First-time sharpening takes approximately 1 minute
- Its countertop format is less suited to buyers prioritizing compact storage
Best for: Households with a mix of 15- and 20-degree kitchen knives, including straight-edge and serrated blades.
Not ideal for: Buyers with only one knife type who want a smaller or non-electric sharpening option.
- Brand:Chef’sChoice
- Model:1520
- Stages:3
- Abrasive:100% diamond
- Compatible blade angles:15 and 20 degrees
- Compatible knives:Straight-edge and serrated
- Dimensions:10 × 4.25 × 4.25 inches
- Weight:4.2 pounds
Our verdict“Pick the 1520 for a mixed-angle kitchen collection; its dual-angle support is more flexible than the 15XV’s 15-degree focus.”
Presto 08800 EverSharp Electric Knife Sharpener
The Presto 08800 keeps the process simple with two sharpening stages and guides that hold a blade at the sharpening angle. Its coarse and fine stages grind, hone, and polish most non-serrated kitchen and sport knives, so it covers more than kitchen prep without the extra stage of the Chef’sChoice 1520 or 15XV. That simpler approach is a good fit for buyers who mainly sharpen standard straight-edge knives and don’t need dual-angle support or broad serrated-knife coverage. The limitation is clear: it handles only one-sided serrated knives, while both Chef’sChoice models listed here support straight-edge and serrated blades. A nonslip base and metal-filings receptacles add practical convenience, but the unit needs a 120 V AC supply.
Pros:- Two coarse and fine stages grind, hone, and polish
- Precision guides help hold the blade at the sharpening angle
- Works with most non-serrated kitchen and sport knives
- Nonslip base and receptacles collect metal filings
Cons:- Does not sharpen most serrated knives
- Requires a 120 V AC power supply
- Offers less stage and blade-angle flexibility than the Chef’sChoice 1520
Best for: Budget-conscious home cooks and sport-knife owners who mostly sharpen non-serrated blades and want guided electric sharpening.
Not ideal for: People who regularly sharpen conventional serrated knives or need support for both 15- and 20-degree edges.
- Brand:Presto
- Model:08800
- Sharpening stages:2 (coarse and fine)
- Compatible blades:Most non-serrated knives; one-sided serrated knives
- Voltage:120 V AC
- Dimensions:8.25 × 5.75 × 4 inches
- Warranty:1-year limited
Our verdict“Choose the Presto 08800 for straightforward sharpening of mostly non-serrated kitchen and sport knives, but look to the Chef’sChoice 1520 if serrated blades are part of your routine.”
Work Sharp E2 Electric Kitchen Knife Sharpener
The Work Sharp E2 is aimed at cooks who want a low-fuss routine rather than control over sharpening angles. Its guided slots hold the blade in position, removing the need to steady an angle by hand. It covers familiar kitchen shapes—chef, santoku, paring, and utility knives—as well as serrated blades, unlike the Presto 08800, which handles only one-sided serrations. Its compact design also makes it easier to tuck away than the countertop-oriented Chef’sChoice 1520. The tradeoff is a narrower job description: the E2 is specified for kitchen knives, while the Work Sharp MK2 can sharpen pocket knives and other tools too. Buyers seeking angle choices or a tool sharpener should look beyond the E2; its appeal is simple guided sharpening and storage.
Pros:- Guided slots make sharpening accessible without angle-holding skill
- Works with chef, santoku, paring, and utility knives
- Supports serrated kitchen knives
- Compact design stores in a drawer or cabinet
Cons:- Requires an electrical outlet
- Limited to kitchen knives
- Provides less stated versatility than the Work Sharp MK2 for non-kitchen tools
Best for: New cooks and busy households who want guided sharpening for common kitchen knives, including serrated blades.
Not ideal for: Knife enthusiasts who want to choose edge angles, or owners who also need to sharpen pocket knives and other tools.
- Brand:Work Sharp
- Model:E2
- Power source:Electric motor
- Compatible knives:Chef, santoku, paring, utility, and serrated kitchen knives
- Design:Compact countertop design
- Sharpening guidance:Guided slots
Our verdict“Choose the E2 for compact, guided sharpening of everyday kitchen knives; the Work Sharp MK2 is the better fit for a broader tool collection.”
Work Sharp MK2 Electric Knife and Tool Sharpener with Replacement Belts
Among these five, the Work Sharp MK2 has the broadest stated job range: its flexible abrasive belts and two-speed motor are designed for kitchen and pocket knives, scissors, axes, lawn mower blades, and other tools. The included 20° / 25° knife guide gives repeatable reference angles, while the second speed offers more control across different sharpening tasks. That makes it a more versatile pick than the kitchen-focused Work Sharp E2, but also a less specialized choice for someone who only needs guided sharpening for chef or paring knives. The belt system and tool compatibility bring flexibility, yet buyers should expect a different format from the enclosed, stage-based Chef’sChoice sharpeners. Replacement belts are included, though the supplied details don’t specify blade compatibility for serrated kitchen knives.
Pros:- Sharpens a wide range of knives and tools
- Two speed settings offer control for different tasks
- Flexible belts and a knife guide support repeatable sharpening
- Includes replacement belts and a 3-year warranty
Cons:- Broader tool capability may be unnecessary for buyers sharpening only kitchen knives
- The listed guide angles are 20° and 25°, with no 15-degree option specified
- Serrated-knife compatibility is not specified in the supplied product details
Best for: Homeowners and cooks who want one electric sharpener for kitchen and pocket knives plus tools such as scissors, axes, and mower blades.
Not ideal for: Buyers who want a dedicated, compact kitchen-only sharpener or need confirmed support for serrated blades.
- Brand:Work Sharp
- Model:WSKTS2-AP-ATL
- Motor:Two speed
- Knife guide angles:20° / 25°
- Included components:Knife sharpener and replacement belts
- Grit type:Medium
- Warranty:3 years
- Dimensions:7.02 × 2.26 × 1.27 inches
Our verdict“Choose the MK2 if you need one belt-based electric sharpener for knives and assorted tools; choose the Work Sharp E2 for a simpler kitchen-only setup.”
How We Picked
I compared the 15 models by the needs that change the buying decision: supported sharpening angles, number and purpose of sharpening stages, blade compatibility, ease of guiding a knife, and versatility beyond kitchen blades. I also looked at practical ownership factors such as replacement abrasives or belts, maintenance demands, and whether a model’s feature set suits occasional touch-ups or a wider range of sharpening tasks. Product names and stated features provide useful distinctions, but they do not establish identical performance across different knives.
The ranking favors clear fit and useful control over a high stage count or a long feature list. The Chef’sChoice 15XV ranks highly for a focused 15-degree kitchen setup, while the Chef’sChoice 1520 and AngleSelect better suit households with both 15- and 20-degree knives. Work Sharp’s MK2 models earn a distinct place for broader knife-and-tool use, while simpler Presto and two-stage options fit buyers who want fewer choices to manage. Scissor slots, multi-function claims, and included replacement belts matter when they match a buyer’s actual needs, not as automatic advantages.
Factors to Consider When Choosing Electric Knife Sharpeners
Before choosing an electric sharpener, I would start with the knives already in your drawer rather than the machine’s headline stage count. Angle compatibility, blade type, sharpening frequency, and how much control you want all affect whether a model is a good match. These broader checks can prevent a convenient-looking purchase from being awkward or unsuitable for your knives.
Match the Sharpening Angle to Your Knives
Knife edges are ground to particular angles, and a sharpener’s guides are built around the angles it supports. A 15-degree-focused machine may suit knives designed for a finer edge, while a model supporting both 15 and 20 degrees offers more flexibility in a mixed collection. Do not assume that every kitchen knife should be sharpened at the same angle just because it fits the slot. Check the knife maker’s guidance when available, especially for specialty or expensive blades. A multi-angle model can reduce guesswork across a household, but it may add controls that a one-angle owner never uses. The right choice is the machine that matches your knives, not the one with the most angle options.
Choose for Blade Types, Not Stage Count
More stages can mean separate steps for shaping, refining, or maintaining an edge, but a larger number does not guarantee a better fit. First check whether the sharpener supports the blade types you own, including straight-edge or serrated knives where relevant. Serrated edges often need a different approach from plain edges, so do not assume a general-purpose slot treats them alike. If your collection is mostly ordinary straight-edge kitchen knives, a simpler guided system may be easier to use consistently. Buyers with varied blades should verify specific compatibility rather than relying on broad claims such as “multi-purpose.” Stage count is most useful when each stage has a clear role for your sharpening routine.
Decide Whether You Need Tool or Scissor Sharpening
Some models in this lineup extend beyond kitchen knives, with Work Sharp’s MK2 aimed at knives and tools and other options advertising scissor slots or multiple functions. Extra capability can make sense when you already sharpen those items and have room for one machine. It can also add complexity if your main task is maintaining a few kitchen knives. Before choosing a multipurpose unit, confirm that its attachments or slots suit the tools you actually own. A dedicated kitchen sharpener may be the more practical choice if you want a guided routine without switching between tasks. Treat versatility as useful only when it replaces a real need, not as a feature to collect.
Balance Guided Ease With Sharpening Control
Electric sharpeners differ in how much they guide the blade and how much attention the user must supply. Guided kitchen models can make angle consistency easier for a beginner, while broader-purpose systems may appeal to someone comfortable managing different blades and tasks. A common mistake is to press hard or make repeated passes in an effort to sharpen faster; that can remove more material than needed. Follow the maker’s instructions for pressure, pass count, and blade placement rather than treating every sharpener as interchangeable. If several people in the home will use the machine, straightforward controls may matter more than extra settings. Buyers who enjoy maintaining tools may accept more involvement in exchange for broader use.
Account for Abrasive Wear and Maintenance
Sharpening surfaces and belts wear with use, so ownership includes more than the initial setup. Check whether the model uses replaceable abrasives or belts and whether replacement parts are available for the version you are considering. Work Sharp’s MK2 package that includes replacement belts may appeal to someone planning regular sharpening, while an occasional user may value a simpler routine instead. Metal filings and residue also make cleanup part of upkeep, so look for the maker’s cleaning instructions before buying. Avoid running a sharpener more often than your knives need; frequent sharpening can remove unnecessary steel. A maintenance plan that fits your habits is more useful than a machine with features you rarely use.
Think About Your Whole Knife Collection
A household with a mix of newer 15-degree knives and traditional 20-degree knives has different needs from someone maintaining one standard set. Inventory the knives you expect to sharpen, including any serrated or specialty blades, and note their recommended edge angles. If you plan to add knives later, a dual-angle sharpener may offer useful flexibility, though it is not automatically the best choice for a fixed collection. Specialty, high-value, or unusually shaped knives may call for a maker-approved sharpening method rather than a general electric unit. A compact, simple model can be a better fit when storage and occasional touch-ups matter most. Buying around the knives you own today—and the ones you are likely to keep—helps avoid paying for capability that will sit unused.
Frequently Asked Questions
Should I choose a 15-degree or 20-degree electric sharpener?
Start with the angle recommended for your knives rather than choosing by reputation or preference alone. A 15-degree-focused sharpener suits knives designed for that edge, while a dual-angle model can serve a household with both 15- and 20-degree knives. Using a sharpener that does not match a knife’s intended edge may change the blade geometry over time. If you cannot find the angle information, check the knife maker’s care guidance before sharpening. For a mixed drawer, angle flexibility can be more useful than adding another sharpening stage.
Can one electric sharpener handle both straight-edge and serrated knives?
Some models are designed to support both, but that does not mean every stage or slot is suitable for every blade. Serrations have angled points and recessed gullets that differ from a plain edge, so they need a method suited to their shape. Check the sharpener’s instructions and the knife maker’s guidance for explicit compatibility before use. If your collection includes valuable or unusual serrated knives, a dedicated service or sharpening method may be safer than assuming a general slot will work. Buyers with mostly straight-edge knives can focus on angle and ease of use instead.
Will an electric sharpener damage an expensive kitchen knife?
It can remove more steel than intended if the angle is mismatched, the knife is used outside the machine’s supported blade types, or the user makes too many passes. Read the knife manufacturer’s care advice and the sharpener’s instructions before sharpening a high-value blade. Guided models can help with consistency, but they do not remove the need to use the correct slot and technique. Some premium or specialty knives may be better suited to a maker-approved service. For everyday knives, use the machine only when the edge needs attention rather than as a frequent routine.
Is a multipurpose knife-and-tool sharpener a good choice for a kitchen?
It can be a sensible choice if you also maintain tools and are comfortable with a system designed for more than kitchen knives. Broader capability may save space and serve varied tasks, but it does not automatically make the machine easier for kitchen-only sharpening. Check whether it offers the guidance and blade compatibility your kitchen knives need, then consider how often you would use the tool-sharpening functions. If you want a simple, repeatable routine for household knives, a dedicated kitchen model may be less complicated. Choose versatility for tasks you genuinely perform, not just for the possibility of future use.
How often should I use an electric knife sharpener?
There is no single schedule that fits every knife, because use, cutting surfaces, and blade steel all affect edge wear. Sharpen when a knife no longer performs well during ordinary kitchen tasks, and follow the instructions for the specific sharpener. Frequent sharpening can remove steel unnecessarily, so a honing routine between sharpening sessions may help maintain an edge, depending on the knife maker’s advice. Avoid using extra passes simply to make the blade feel sharper. If performance remains poor after careful sharpening, the blade may need repair or a different sharpening method.
Conclusion
For most kitchen-focused buyers who want a dedicated 15-degree option, I would start with the Chef’sChoice 15XV EdgeSelect as the best overall pick. The Presto 08810 EverSharp is my best-value direction for shoppers who prefer a straightforward three-stage kitchen sharpener, while the Chef’sChoice 1520 or AngleSelect makes more sense as a premium choice when both 15- and 20-degree knives need support. Beginners should favor a guided, uncomplicated kitchen model and confirm its angle matches their knives before buying. For specific needs beyond kitchen blades, I would look to the Work Sharp MK2 for knife-and-tool sharpening, or to a scissor-slot option only if scissor care is part of the plan. The right choice is the one that fits your blades and routine—not simply the model with the most stages or features.
