The 5 best kitchen knife sharpeners
1. Chef’sChoice Trizor XV EdgeSelect
Why we picked it: the patented three-stage system converts any knife — even 20° European edges — to a sharper 15° Trizor XV triple-bevel edge, and the result is genuinely sharper than factory-new. Flexible spring guides hold the angle for you, so consistent results don’t depend on technique. It’s the best electric sharpener you can buy for a busy kitchen.
Pros
- Edge sharper than factory-new knives
- Converts 20° edges to a sharper 15° triple bevel
- Spring guides hold a consistent angle
- Works on straight and serrated blades
Cons
- Premium price
- Not for single-bevel Japanese knives

Why we picked it: it’s the highest-rated budget knife sharpener on Amazon, with over 60,000 reviews, and at under $10 it delivers surprisingly effective results for such a simple tool. A coarse carbide stage sets the edge, a fine ceramic stage hones and polishes, and the non-slip rubber base grips any countertop edge. There’s zero learning curve.
Pros
- Incredibly affordable
- Dead simple — zero learning curve

3. Lansky Deluxe 5-Stone Sharpening System
Why we picked it: this guided whetstone system bridges the gap between freehand sharpening and electric sharpeners. With five grits from extra-coarse to ultra-fine and four angle settings, it can restore virtually any blade to mirror-polish sharpness — and the guide rods remove the guesswork that makes freehand stones so hard to learn. It’s the cooker to buy when you want the sharpest possible edge.
Pros
- Sharpest edge possible — mirror-polish capable
- Multiple angle settings (17°–30°)
- Five grits handle repair through polishing
- Guided system removes the guesswork
Cons
- Slower — 15–30 min per knife
- Clamp struggles with very short blades
4. Work Sharp Culinary E5 Electric Sharpener
Why we picked it: the E5 takes a different approach with flexible abrasive belts instead of fixed stones — a design that’s gentler on blades while still delivering a razor edge quickly and consistently. Adjustable guides cover both 15° and 20° knife styles, an included ceramic rod handles between-sharpening maintenance, and it runs quieter than stone-based electrics. At roughly $80–100 it’s the value play in electric sharpening.
Pros
- Flexible belts are gentler than rigid stones
- Adjustable 15° and 20° angle guides
- Ceramic honing rod included
- Quieter than stone-based electrics
Cons
- Belts need periodic replacement
- Slightly slower than the Trizor XV
5. Wusthof 4-Stage Handheld Sharpener
Why we picked it: it brings German engineering from a knife brand trusted since 1814 to a simple handheld design. Four stages — pre-set, coarse, fine and ultra-fine — cover everything from edge repair to final polishing at a consistent 14° per side, ideal for Western knives. It’s compact, portable, and genuinely easy to use with no learning curve.
Pros
- Made by Wusthof — trusted since 1814
- 4 stages from repair to polishing
- Consistent 14° angle for Western knives
- Compact, portable, no learning curve
Cons
- Pricier than basic pull-throughs
- Only suits Western-style angles
Knife sharpener buying guide
Electric vs. manual. Electric sharpeners are the fastest and most consistent, ideal for busy cooks who want sharp knives with minimal effort — but they remove more metal per session, so over-use shortens a blade’s life. Manual sharpeners give you more control and are gentler: pull-throughs are easy, whetstones give the best results but take skill, and both are portable and need no power.
Grit levels. Coarse (120–400) reprofiles damaged or very dull blades; medium (600–1000) handles regular sharpening of moderately dull knives; fine (2000–3000) refines and polishes the edge; ultra-fine (4000–8000) is for mirror-polish finishing, the realm of Japanese knives.
How often to sharpen. Most home cooks should sharpen every 2–3 months with a coarse/medium sharpener. Between sharpenings, use a honing steel before each cooking session — it doesn’t remove metal, it just straightens the microscopic edge that bends during use.

Frequently asked questions
What’s the difference between an electric sharpener, a pull-through, and a whetstone?
They trade speed for control. Pull-throughs like the KitchenIQ 50009 are cheapest and easiest, drag the blade through fixed carbide and ceramic slots, but remove more metal and lock you to one angle. Electric sharpeners like the Chef’sChoice Trizor XV are fast and consistent thanks to guides that hold the angle for you, ideal for busy kitchens. Whetstones, especially a guided system like the Lansky, give the sharpest, most polished edge and the most control, but they’re slow and have a learning curve. Pick based on how much time and precision you want.
Will a knife sharpener ruin or wear down my knives over time?
Any sharpener removes metal, so used correctly none should ‘ruin’ a knife, but how much they remove varies. Electric models like the Chef’sChoice Trizor XV and aggressive pull-throughs like the KitchenIQ take off more steel per pass, so the honest rule is to sharpen only when a blade is actually dull, not as a habit. Belt-driven and whetstone systems like the Work Sharp E5 and Lansky are gentler. Between sharpenings, use a honing rod to realign the edge, which extends blade life and reduces how often you need to remove metal at all.
Can I sharpen Japanese or serrated knives with these sharpeners?
It depends on the tool and the blade. Most pull-throughs, including the KitchenIQ, use a fixed Western angle that’s wrong for expensive Japanese knives; for those, a guided whetstone like the Lansky lets you match the steeper Japanese bevel. Single-bevel Japanese knives generally shouldn’t go in electric two-sided sharpeners at all. For serrated blades, the Chef’sChoice Trizor XV has a dedicated stage that handles them, whereas most sharpeners only touch straight edges. Always confirm the sharpener supports your specific blade type before using it.
What sharpening angle should I use, 15 or 20 degrees?
As a rule of thumb, Western and German knives are traditionally ground around 20 degrees, while Japanese and finer blades favor a keener 15 degrees. A lower angle is sharper but slightly more fragile; a higher angle is more durable. Sharpeners handle this differently: the Chef’sChoice Trizor XV actually converts 20-degree European edges to a sharper 15-degree triple bevel, the Work Sharp E5 offers both 15- and 20-degree guides, and the Lansky spans 17 to 30 degrees. When in doubt, follow the angle your knife maker specifies.
Is an expensive sharpener worth it, or is a cheap pull-through good enough?
For many home cooks, the under-$10 KitchenIQ 50009 is genuinely good enough; it’s the highest-rated budget sharpener on Amazon with 60,000-plus reviews, has zero learning curve, and quickly restores everyday Western knives. You step up to something like the Chef’sChoice Trizor XV or Lansky when you own pricier or Japanese knives, want a noticeably finer edge, or sharpen often and value consistency and gentler metal removal. Match the tool to your knives: a budget pull-through for inexpensive blades, a premium system to protect and maximize a serious collection.
