The Best Knife Sharpeners: 4 Compared (and One to Skip)

We compared two electric sharpeners, a Japanese whetstone, and a rolling sharpener on edge quality, ease of use, and metal removal.

RBE top pick

Chef'sChoice Trizor XV (Model 15XV)

For most people the Chef'sChoice Trizor XV is the safest recommendation: it delivers a consistently sharp, durable edge in about a minute with no skill required. If you own good knives and enjoy the process, the inexpensive Tojiro whetstone produces an even better edge and removes far less metal over a blade's lifetime.

New to knife sharpeners? Our plain-English Knife Sharpeners, Explained guide decodes every spec first.

A dull knife is more dangerous and more frustrating than a sharp one, but the right way to fix it depends on how much control you want and how much you enjoy the process. We synthesized independent testing and owner reports across four current 2026 options: two push-button electric sharpeners, a classic Japanese waterstone, and a design-forward rolling sharpener. Two earn a clear buy, one is a genuine it-depends, and one is hard to justify for most kitchens.

Which one is right for you?

How we judged the field

We do not run our own sharpening lab. Instead we synthesized independent testing, expert write-ups, and aggregated owner reports for each tool, then weighed them against the criteria that actually matter in a home kitchen. The biggest ones were edge quality and consistency (how sharp the result is, and whether you can repeat it), ease of use (how much skill and patience it demands), and how much metal the tool removes, since aggressive sharpening shortens a knife’s life. We also looked at angle control, the range of knives each tool handles, upkeep, and whether the price is justified by the result. The field spans two philosophies: push-button electrics that trade some metal and control for speed, and manual tools that reward technique with a finer, longer-lasting edge.

Chef’sChoice Trizor XV (Model 15XV) — buy

This is the sharpener to buy if you just want sharp knives with zero fuss. Its three-stage system uses diamond abrasives to shape and sharpen, then a flexible stage to strop and polish, and spring-loaded guides hold the angle for you from heel to tip. Independent testing repeatedly ranks it at or near the top of electric sharpeners, and owners note it takes roughly a minute per knife and reliably converts dull, thick factory edges into a keener 15-degree edge that bites into tomatoes and onions cleanly. The honest trade-offs: it is bulky, it is not quiet, and like any motorized sharpener it removes more metal than a stone. But for consistency-per-effort, nothing else here competes.

Work Sharp Culinary E5 — it depends

The E5 takes a different approach to electric sharpening, running flexible abrasive belts that conform to the edge in a way rigid wheels cannot. It is fast, offers shape, sharpen, and hone modes, and with the guide kit adds 15- and 20-degree angle control for both Eastern and Western edges. Reviewers describe results that rival or beat a manual block for many users. Why the qualified verdict? It sits at the very top of the electric price bracket, the belts are a consumable you will replace over time, and the belt action is a little more aggressive and less forgiving than a stone if you hurry a pass. It is an excellent tool for the cook who wants electric speed but still likes to feel involved; it is overkill for someone who simply wants to press a button.

Tojiro Combination Whetstone #1000/#3000 — buy

Dollar for dollar, this is the best edge here. The 1000-grit side reprofiles and sharpens while the 3000-grit side refines and polishes to a fine finish, and the non-slip base keeps everything stable and safe. Owner reports are full of people describing knives sharper than they have ever been, and because a stone shaves off only a whisker of steel, your knives can last for decades of regular sharpening. The catch is honest and unavoidable: there is a real learning curve. Your first edges will be worse than an electric would give you, and the stone needs soaking and occasional flattening. Push through a few sessions, though, and you will out-sharpen every powered tool on this list for a fraction of the price.

Horl 2 Rolling Knife Sharpener — skip

The Horl 2 is genuinely lovely: solid wood, a clever magnetic angle support that makes holding 15 or 20 degrees easy for beginners, and it does remove nicks and restore a working edge far better than pull-through gadgets. The problem is value. It costs more than either electric sharpener while giving you only two fixed angles and two discs, and owners report it fumbles with long blades that flex and narrow blades that sit too low on the magnet. You are paying a large premium mostly for design. If you will genuinely never touch a whetstone and want something beautiful on the counter, it is defensible, but for almost everyone the money is better spent elsewhere.

Chef’sChoice Trizor XV vs Tojiro whetstone: which should you buy?

These are the two we would actually recommend, and the choice comes down to temperament. The Chef’sChoice Trizor XV wins on speed and certainty: press, pull, done, with a consistent edge every time and no skill required. It is the right answer for a busy household, a shared kitchen, or anyone who views sharpening as a chore to be finished. The Tojiro whetstone wins on the two things enthusiasts care about most, ultimate edge quality and blade longevity, and it does so for a fraction of the price, asking only your time and patience in return. If you want the job done in a minute, buy the Chef’sChoice. If you own knives worth caring for and are willing to learn, the Tojiro will make them sharper than any machine and outlive several electrics.

What to look for

  • Match the tool to your patience. Electrics reward convenience; stones reward practice. Be honest about which you are.
  • Mind the angle. Look for a tool that suits your knives, roughly 20 degrees for most Western blades and 15 for many Japanese ones.
  • Consider metal removal. The more aggressive the tool, the faster your knives wear; a stone is gentlest.
  • Factor in consumables. Belts and discs add ongoing cost that a stone does not.
  • Do not overpay for looks. A great edge does not require a premium price tag.

Our final take

Buy the Chef’sChoice Trizor XV if you want reliably sharp knives with no learning curve; it is the best all-around pick for most kitchens. Buy the Tojiro whetstone if you own good knives and enjoy the craft, because it delivers the finest edge here for the least money while barely wearing your blades. Consider the Work Sharp E5 only if you specifically want electric speed with some hands-on control and do not mind paying for it. And skip the Horl 2 unless its design alone sells you, because it costs more than the electrics without out-sharpening a simple stone.

Questions, answered

Do electric sharpeners ruin your knives?

They do not ruin knives, but powered diamond or belt sharpeners remove more metal than a stone with each use. Over many years that shortens a blade's life. Reviewers and owners consider models like the Chef'sChoice Trizor XV safe for everyday knives; enthusiasts with expensive blades often prefer a whetstone precisely because it removes so little steel.

Is a whetstone worth the learning curve?

For anyone who owns good knives and sharpens regularly, yes. Independent testing and owner reports consistently find that a waterstone produces the keenest, longest-lasting edge and preserves the blade best. The trade-off is that your first few attempts will be worse than an electric sharpener until your technique develops over a handful of sessions.

What angle should I sharpen my kitchen knives at?

Most Western knives are ground around 20 degrees per side and many Japanese knives around 15 degrees, which is why guided tools offer those two settings. A lower angle like 15 degrees cuts more keenly but is slightly more delicate. The Chef'sChoice Trizor XV standardizes most knives to a durable 15-degree edge, while a whetstone lets you match whatever angle a blade was designed for.

Can these sharpen serrated or Japanese single-bevel knives?

Most of these tools are built for standard double-bevel straight edges. Serrated bread knives generally need a dedicated tapered rod or professional service, and traditional single-bevel Japanese knives are best done on a stone by someone experienced. Check each manufacturer's guidance before sharpening specialty blades.

Is the Horl 2 better than a cheap whetstone?

Not in terms of the edge it produces. Owner reports credit the Horl 2 for making consistent results easy for beginners, but it costs far more than a quality stone while offering only two fixed angles. If your goal is the sharpest possible edge for the money, a whetstone wins; the Horl's appeal is its looks and its guided simplicity.
