Best electric overall
Chef'sChoice 15XV EdgeSelect Professional Electric Knife Sharpener
The kitchen electric to beat: a dedicated 15 degree edge, diamond abrasives, and three stages that take a knife from dull to polished without guesswork.
Strengths
- The dedicated 15 degree edge suits precision slicing and converts traditional 20 degree factory edges, so one machine covers both European and Japanese style kitchen knives.
- Three stages separate the work sensibly: reshaping, honing, and stropping to a polished finish, rather than asking one slot to do everything.
- Diamond abrasives cut faster than ceramic alone, so a truly dull knife comes back in a few passes instead of a long, tiring session.
Limitations
- It is built for kitchen knives first, so very thick outdoor blades and tools are better served by a belt sharpener like the Work Sharp Ken Onion.
- The machine needs counter space and a power socket, and it is not something you tuck into a drawer after use.
- An electric machine removes steel quickly, so a light touch matters: pressing hard or over-sharpening shortens a blade's life for no benefit.
What owners report
Commonly praised
- Knives come back keen after just a few slow passes through the three stages
- The fixed angle removes all guesswork for owners who never learned freehand sharpening
- Even older kitchen knives feel useful again instead of heading for replacement
Common complaints
- The machine takes up real counter space and needs a socket nearby
- A heavy hand can take off more steel than a careful owner would like
- It is overkill for anyone who only sharpens one or two basic knives

| Stages | 3 stages |
|---|---|
| Edge angle | 15 degrees |
| Abrasive | 100% diamond abrasives with stropping disks |

Best for: Home cooks who want the fastest, most foolproof route to a genuinely sharp kitchen knife, including Japanese style blades.
Skip if: You want to control the angle yourself, you sharpen mainly pocket or outdoor knives, or you dislike countertop appliances.
Best electric for mixed drawers
Chef'sChoice 1520 AngleSelect Electric Knife Sharpener
The mixed-drawer electric: choose a 15 degree edge or a traditional 20 degree edge, with diamond abrasives and precision angle guides in both slots.
Strengths
- AngleSelect gives you both common kitchen angles in one machine, so no knife in the drawer has to be sharpened at the wrong angle.
- Precision angle guides hold the blade steady through each pass, which is the part beginners usually get wrong with a freehand tool.
- The final stropping stage polishes the edge, so knives leave the machine smoother and keener than a single-stage electric can manage.
Limitations
- It is still a countertop electric, so it needs a socket and a permanent-ish home near where you prep.
- The two-angle flexibility adds a decision at every use: picking the wrong slot for a knife gives a workable but not ideal edge.
- Like any electric, it removes more steel than a whetstone session, so it is a maintenance tool, not a daily habit.
What owners report
Commonly praised
- Having both kitchen angles in one box ends the worry about sharpening a knife at the wrong angle
- The polished finish leaves edges feeling smooth rather than rough or toothy
- Santoku and everyday European knives can finally share one sharpener
Common complaints
- Choosing the right slot each time trips up owners who have never checked a knife angle
- The unit is another appliance to find a home for in a small kitchen
- Daily sharpening is unnecessary, yet the machine tempts owners to overuse it

| Angle selection | 15 degrees or 20 degrees |
|---|---|
| Abrasive | 100% diamond abrasives |
| Edge | Two-facet arch-shaped edge |
| Knives | Straight edge and serrated knives, including Santoku |
| Guides | Precision angle guides |
Best for: Households with a mixed knife drawer: German style knives at 20 degrees alongside Japanese style knives at 15 degrees.
Skip if: Every knife you own is 15 degrees, in which case the 15XV is the more focused machine, or you want a manual tool.
Best electric for knives and tools
Work Sharp Ken Onion Edition Mk.2 Knife and Tool Sharpener
The do-everything belt machine: flexible abrasive belts, adjustable guides, and speed control for kitchen knives, scissors, and workshop tools alike.
Strengths
- Flexible abrasive belts follow the blade and produce a keen, consistent edge quickly, even on knives that a slot sharpener struggles with.
- Adjustable sharpening guides cover bevels from 15 to 30 degrees, so one machine suits delicate kitchen edges and sturdier tool edges.
- Variable speed with an LED display lets you grind slowly for honing and faster for reshaping, instead of one speed for every job.
Limitations
- A belt machine removes steel fast, so a heavy hand or a long pass can round a tip or overheat a thin edge.
- Belts are consumables, so long-term cost includes replacements, unlike a stone or diamond wheel system.
- It is a workshop-flavoured machine in size and noise, less at home on a small kitchen counter than a compact Chef'sChoice.
What owners report
Commonly praised
- One machine handles kitchen knives, scissors, and garden tools without buying separate gadgets
- Belt changes are quick, and the speed control makes delicate work feel controlled
- Blades that other sharpeners struggled with come back sharp in short order
Common complaints
- Belts wear out and need replacing, which adds an ongoing cost
- The machine is louder and bulkier than a quiet kitchen slot sharpener
- Beginners can round a tip if they rush a pass at high speed

Skip if: You only sharpen kitchen knives and want the simplest possible machine, or belts and speed settings sound like more machine than you need.
Best value electric
Presto EverSharp Electric Knife Sharpener 08800
The straightforward value electric: two stages, automatic guides, and a razor edge for everyday non-serrated kitchen knives.
Strengths
- Two stages keep the routine simple: one stage sharpens, the second hones, with no angle decision to make.
- Automatic blade guides hold the knife at the right angle, so results do not depend on a steady hand.
- It is compact and inexpensive for an electric, so it fits kitchens where a premium Chef'sChoice feels like overkill.
Limitations
- It is designed for most non-serrated knives, so serrated bread knives need a different tool.
- There is no angle selection, so owners of 15 degree Japanese knives should look at the 15XV or the 1520 instead.
- The finish is a good working edge rather than the polished edge a stropping stage produces.
What owners report
Commonly praised
- Two stages and nothing to decide make it the simplest electric many owners have used
- Everyday knives come back to a clean working edge in minutes
- The modest size fits kitchens where bigger machines would dominate
Common complaints
- Serrated bread knives need a different tool, which surprises some buyers
- There is no angle choice for owners with Japanese style knives
- The finished edge is good rather than mirror-polished
Recurring themes from owner reviews on retailers and forums, summarised by our editors. Updated October 2026.
| Stages | 2 stages |
|---|---|
| Knives | Most non-serrated kitchen and sport knives |
| Guides | Automatic blade guides |
| Power | 120 volts, electric |
| Design | Compact countertop electric |
Best for: Everyday cooks who want an electric sharpener at a modest outlay and sharpen standard straight-edge kitchen knives.
Skip if: You need serrated sharpening, a 15 degree Japanese edge, or a machine that also handles tools and scissors.
Best non-electric alternative
Chef'sChoice AngleSelect Manual Sharpener 4633
The Chef'sChoice angles without the socket: diamond wheels in 15 and 20 degree slots, in a manual sharpener that lives in a drawer.
Strengths
- Separate 15 and 20 degree diamond slots mean mixed drawers get the right angle without an electric machine on the counter.
- Diamond abrasives cut more effectively than the carbide slots on cheaper pull-throughs, so fewer passes restore the edge.
- The compact footprint fits a drawer or a small kitchen, and it works anywhere, with no socket or setup.
Limitations
- A manual pull-through cannot reprofile a chipped or very dull edge the way a coarse stone or electric stage can.
- Pulling technique still matters: uneven pressure or speed gives an uneven edge, even with guides.
- There is no stropping stage, so the finish is a sharp working edge rather than a mirror-polished one.
What owners report
Commonly praised
- The diamond slots restore an edge with fewer passes than cheaper carbide pull-throughs
- Living in a drawer means it is always at hand when a knife drags
- No socket or noise makes it easy to use any time of day
Common complaints
- A truly dull or chipped knife needs more than this manual tool can offer
- Uneven pulling pressure gives an uneven edge until technique improves
- The finish stops short of the polished edge an electric stropping stage gives

| Stages | 2 stages |
|---|---|
| Angle slots | 15 degrees and 20 degrees |
| Abrasive | Diamond wheels |

| Design | Compact manual pull-through |

Skip if: You have a truly dull or damaged knife that needs reshaping, or you want a polished, stropping-stage finish.
Questions, answered
Do electric sharpeners damage knives?
They remove steel faster than stones, so heavy pressure or too many passes can shorten a blade's life, but used lightly and only when the knife is actually dull, a good electric is safe for everyday knives. Prized Japanese knives deserve a lighter touch or a whetstone.
Can electric sharpeners sharpen serrated knives?
Some can, including the Chef'sChoice 15XV and 1520, which list serrated knives among their supported types. Many value electrics, including the Presto EverSharp, are designed for straight-edge knives only, so check the listing before ordering for a bread knife.
Do I need to replace anything on an electric sharpener?
Diamond wheels and ceramic disks last a long time under home use, while belt machines like the Ken Onion need replacement belts as a consumable. Neither needs frequent attention, but belt owners should factor replacement belts into the long-term cost.
