The 8 Best Electric Knife Sharpeners, Reviewed
Chef’sChoice Trizor XV (15XV EdgeSelect)
- 3-stage
- Converts 20° → 15°
- 100% diamond abrasives
- Straight & serrated
- $$$
The near-universal top pick among testers, and our winner too. Its 3-stage diamond system converts a standard 20° factory edge into a stronger, sharper 15° edge in about a minute, with flexible spring guides that take the guesswork out of holding the angle. Later touch-ups take about 10 seconds.
Chef’sChoice Model 1520 AngleSelect
- Does 15° & 20°
- Diamond abrasives
- Stropping stage
- Straight & serrated
- $$$
If your kitchen mixes Western (20°) and Japanese-style (15°) knives, this is the one. AngleSelect lets you apply either edge, so one machine handles a German chef’s knife and a santoku equally well. A patented stropping stage finishes with a polished, long-lasting edge.
Work Sharp Culinary E5
- Flexible belts
- 3 presets
- Under 90 sec
- Knives, scissors & shears
- $$
The only home sharpener using flexible belts — the same method knife makers use — for smooth, factory-style edges on any brand or steel. Three one-button settings (shape, sharpen, hone) plus a built-in vacuum that keeps grinding debris off your counter. It even does kitchen scissors and poultry shears.
Work Sharp Ken Onion Edition
- Adjustable 15°–30°
- Variable speed
- Knives, scissors, serrated & tools
- 3-yr warranty
- $$$
Designed with knife-making legend Ken Onion, this is the most versatile sharpener on the list. Fully adjustable 15°–30° angles and electronic speed control let you dial in everything from a delicate paring knife to a cleaver — plus scissors, serrated blades, and workshop tools.
Wüsthof Easy Edge
- 3-stage
- One-touch presets
- Shape · Sharpen · Refine
- Made in USA
- $$$
From the storied German cutlery brand, the Easy Edge keeps it foolproof: three pre-programmed one-touch buttons walk you through repairing, sharpening, and refining with zero guesswork. Use Shape for a very dull or damaged blade, Sharpen monthly, and Refine weekly to maintain the edge.
SHARPAL 198H Electric Knife Sharpener
- 3-in-1 slots
- 20° angle
- Diamond wheels
- Genuinely quiet (<65 dB)
- $$
A lot of sharpener for the money. The 3-in-1 slots handle chef’s knives, pocket knives, and more, and the fixed 20° guides keep the angle consistent without any skill. It runs genuinely quiet, resists overheating, and the magnetic tray catches metal filings for easy cleanup.
Chef’sChoice 250 Diamond Hone Hybrid
- Electric + manual
- 3-stage
- Diamond abrasives
- 20° · straight & serrated
- $
The best of both worlds: electric speed for the first stages, a manual stage for control at the finish. Diamond abrasives and Trizor-engineered facets build a durable, arch-shaped 20° edge. A great-value pick for anyone who sharpens regularly but wants a hand in the final polish.
Presto 08800 EverSharp
- 2-stage
- Sapphirite wheels
- Automatic blade guides
- Non-serrated
- $
The people’s champion — tens of thousands of reviews and a price anyone can justify. Its simple 2-stage system with automatic blade guides grinds and then hones most straight-edge knives to a razor edge in seconds. No frills, no fuss, and it just works.
How to Choose the Right Electric Knife Sharpener
Stages
2-stage sharpeners are simple and budget-friendly for straight edges; 3-stage models add a polishing/stropping step for a finer, longer-lasting, pro-level edge.
Edge angle
Most Western knives are 20°; Japanese-style knives are 15°. Some sharpeners (like the Trizor XV and 1520) convert or do both — key if you own a mix.
Serrated & tools
Not every sharpener handles serrated knives, scissors, or tools. If you own them, pick a model that lists them (Ken Onion and Work Sharp E5 are the most versatile).
Corded vs. cordless
Nearly all quality electric sharpeners are corded — battery-powered units rarely have the torque for a consistent edge. Plan for an outlet near your counter.
Noise & cleanup
Look for a quiet motor (under ~65 dB) and a debris tray or built-in vacuum. Metal filings are the messiest part of sharpening.
Home use vs. pro
For everyday home use, a 2–3 stage guided sharpener is plenty. Go pro-grade (diamond, adjustable) only if you sharpen often or own expensive knives.
