Best knife sharpener 2026: our comparison of 6 models
By Charles NeveuUpdated on 07/10/2026AnalysedEditor's review6 models compared
For most kitchens, the best knife sharpener is the HORL 3: a rolling sharpener that holds the angle for you, at 15 or 20 degrees, for 169.00 euros on 7 October 2026. On a tight budget, the Wüsthof Precision Edge pull-through sharpener costs 22.30 euros, but its angle is fixed and its carbide removes more metal.

The best knife sharpener is the one that holds the right sharpening angle for you without wearing the blade away for nothing: for most kitchens, that is a rolling sharpener like the HORL 3. I compared the listings of 20 models across the five families of tools (rolling sharpener, electric sharpener, whetstone, pull-through sharpener and honing steel) from HORL, Wüsthof, Graef, King, Chef'sChoice, Zwilling, Victorinox, Global, Kai, Naniwa and Miyabi, checked their prices on 7 October 2026 and matched each one to a profile. To compare the families of tools before choosing a model, see our knife sharpener page; for the blade itself, our selection of kitchen knives.
How we compared
This comparison is based on reading the product listings, not on hands-on testing: none of these sharpeners has been used by our team, hence the "Editor's review" badge. I checked 20 listings on Amazon and kept the 6 that cover each profile with an active offer on 7 October 2026, sold by Amazon or by the brand wherever possible.
For each one, I recorded the price, availability and seller on Amazon, then cross-checked the sharpening angle, the abrasive, the number of stages, the grit and the country of manufacture against the manufacturer's page. A value that cannot be found or is contradictory is marked "n.c.". We do not use Amazon customer ratings or other sites' rankings.

The 6 best knife sharpeners in detail
Each model is presented with the profile it suits, its drawback first, then what sets it apart.
HORL 3: our top pick, the rolling sharpener
Who it is for: sharpening every kitchen knife, from chef's knife to santoku, without learning to hold the angle by hand.
What nobody tells you: at 169.00 euros on 7 October 2026, it is the most expensive in the selection apart from the electric one, for just two angles. The finer surfaces that lead to a mirror edge are sold separately by HORL, as kits.
What I liked: the principle solves the number one problem of sharpening, a constant angle. The blade sits against a magnetic stand that sets the angle, at 15 or 20 degrees, and you roll the cylinder along the edge. One diamond face sharpens, the other, in ceramic, removes the burr, the thin lip of metal that forms at the edge. The Quick Lock system lets you swap sharpening surfaces in one move, and the solid wood body is made in the Black Forest according to HORL.
Who it is for: the same rolling principle as the HORL 3 for 50 euros less, as a first sharpener.
What nobody tells you: its discs are fixed. You cannot add a finer surface, and deburring is done on a stainless steel surface instead of the ceramic one on the HORL 3.
What I liked: it keeps the essentials for 119.00 euros on 7 October 2026: the same magnetic stand at 15 and 20 degrees, the same standard diamond surface, and HORL presents it as the model for beginners, also suited to pocket knives. Its body is made of recycled plastic collected at sea, and it is made in the Black Forest. When we checked, the offer was sold by HORL on Amazon.
Wüsthof Precision Edge: budget pick, the pull-through sharpener
Who it is for: giving everyday kitchen knives their bite back in a few seconds, for little money.
What nobody tells you: the angle is set by the slot and Wüsthof does not publish it on the Amazon listing. The first slot, in tungsten carbide, strips metal on every pass: it is meant for a dull knife, not for weekly upkeep.
What I liked: at 22.30 euros on 7 October 2026, it is the simplest in the selection. Two slots: the carbide reshapes the edge, the ceramic polishes it. You pull the blade from heel to tip, holding the handle with the other hand, with the non-slip base on the worktop. It weighs 238 g and was sold and shipped by Amazon when we checked.
King 1000/6000 whetstone: for a razor edge, Japanese knives included
Who it is for: cooks willing to learn a technique to get the finest edge, on a Japanese knife as well as a European one.
What nobody tells you: nothing holds the angle for you. You have to keep it constant by hand, soak the stone before each session and flatten it from time to time, as it wears hollow in the middle.
What I liked: at 39.89 euros on 7 October 2026, it is the most classic two-sided whetstone: a 1000 grit to sharpen, a 6000 grit to polish, on a base that comes with it. You choose the angle, so it handles a santoku at 15 degrees as well as a chef's knife at 20 degrees, and it removes little metal. It is made in Japan by King Toishi (reference HT-65) and measures 18.5 x 6.3 x 2.5 cm.
Graef CC120: the electric sharpener for European knives
Who it is for: quickly sharpening a whole set of European knives, with no technique to learn.
What nobody tells you: it has only one angle, 20 degrees, which does not suit thin blades sharpened at 15 degrees. It is also the bulkiest in the selection, and its diamond wheels remove metal on every pass.
What I liked: three stages in a row, from sharpening to polishing, with guides that present the blade at the angle. The third stage also takes serrated blades, according to Graef. At 124.09 euros on 7 October 2026, sold and shipped by Amazon when we checked, it is the simplest answer to "which electric knife sharpener should I choose?" when most of your knives are German or French.
Wüsthof 23 cm honing steel: for maintaining the edge between sharpenings
Who it is for: keeping a chef's knife sharp day to day, alongside one of the sharpeners above.
What nobody tells you: a steel honing rod does not sharpen a dull knife, it realigns the edge. Wüsthof does not publish its hardness, and a steel rod does not suit very hard Japanese blades.
What I liked: it is the cheapest tool in the selection, 23.70 euros on 7 October 2026, and the quickest: a few strokes on each side before cooking are enough to straighten an edge that has rolled. Its 23 cm length covers a 20 cm chef's knife. Made in Germany, sold and shipped by Amazon when we checked.
A well-sharpened knife cuts cleanly, needs less force and slips less: it is more precise and safer than a dull blade.
A sharp knife reduces the risk of injury
Contrary to what you might think, a sharp edge causes fewer injuries than a dull one. A blade that cuts badly forces you to press, and it is under pressure that it skids off the skin of a tomato or an onion. A blade that bites into the food moves forward on its own, and the hand holding the food stays where it is.
Regular knife maintenance
An edge wears and bends with every cut, especially on a hard board. Maintenance comes down to two actions: realign often, with a honing steel or a fine stone, and sharpen now and then, when the steel is no longer enough. How often depends on your cooking, not on a calendar: the right signal is a tomato whose skin resists.
Fixed, unpublished angle, and tungsten carbide removes more metal than a stone: keep it for genuinely dull knives.
A steel rod realigns the edge but does not sharpen a dull knife, and it does not suit very hard Japanese blades.
You have to learn to hold the angle by hand and soak the stone before each session, and it dishes over time.
Fixed discs: you cannot add a finer surface, and deburring is done on stainless steel rather than ceramic.
A single 20-degree angle, unsuited to Japanese knives sharpened at 15 degrees, and a bulky machine that removes metal on every pass.
The most expensive in the selection apart from the electric one, limited to two angles, and the finer discs cost extra.

The HORL-style rolling sharpener
A rolling sharpener combines a magnetic stand, which sets the angle, and a cylinder with two discs that you roll along the blade. It is the best compromise between the finesse of a stone and the simplicity of a machine: the angle is constant, the diamond works quickly and the finishing disc removes the burr. HORL invented the principle, and cheaper copies have appeared since; we did not keep any, for lack of a manufacturer's page to cross-check.
The electric sharpener: which model to choose?
An electric sharpener spins abrasive wheels behind guides that set the angle. It is the fastest for a whole set of knives, but it removes more metal than a stone and often offers only one angle. To choose, look at the angle (20 degrees for European knives, 15 degrees for thin blades), the number of stages, whether there is a slot for serrated blades, and the voltage if the appliance is imported.
The pull-through sharpener
A pull-through sharpener is a small tool where you draw the blade through a V-shaped slot, often in two stages: tungsten carbide or diamond to reshape the edge, ceramic to polish it. It costs little and needs no technique, but the angle is fixed and carbide wears the blade. Keep it for everyday knives rather than a Japanese carbon steel knife.
The honing steel: realigning rather than sharpening
A honing steel is a rod of steel, ceramic or diamond-coated metal along which you draw the blade at a shallow angle to realign the edge. A classic steel rod maintains a European knife; a ceramic rod, which removes a little metal, suits harder steels better. Choose a rod longer than the blade: 23 cm for a 20 cm chef's knife.
The whetstone: how to choose the right sharpening stone?
A water stone, or whetstone, removes a thin layer of metal by friction on a wet surface. Its grit tells you how abrasive it is: the lower the number, the coarser the grit.
Grit
Use
When
120 to 400
Coarse sharpening
Chipped or very dull blade
700 to 2000
Regular sharpening
Bringing back the edge on a worn blade
3000 to 8000
Finishing and polishing
Removing scratches, razor edge
To start, a 1000/3000 or 1000/6000 combination stone is enough: a medium grit to sharpen, a fine grit to finish. Above 8000, there is no reliable grit measurement from one maker to another, and the gain becomes minimal for kitchen use.
The sharpening angle: 15 or 20 degrees
The sharpening angle is the angle between the blade and the abrasive, measured on each side. A 15-degree angle gives a finer edge, suited to thin blades in hard or Damascus steel, but more fragile; a 20-degree angle gives a sturdier edge, suited to European knives. Stick to the original angle set by your knife's maker when it is published.
How to sharpen a knife on a whetstone?
You sharpen a knife on a whetstone in three steps: prepare the stone, work the blade at a constant angle from coarse to fine grit, then finish on leather.
Preparing the stone
Soak the stone in water until air bubbles stop rising (the time varies from stone to stone: follow its instructions), then set it on its base or on a damp towel, coarsest grit facing up. Never use oil on a water stone: water is enough and oil clogs its pores. Keep a bowl of water within reach to wet the surface during the session.
Sharpening technique
Set the blade at the chosen angle and make regular back-and-forth strokes with the same pressure, working section by section: the heel, the middle, then the tip. When you can feel a slight burr under your finger on the other side of the edge, switch to the other face. Then turn the stone over and repeat on the fine grit to polish the edge. A tip to check the angle: colour the bevel with a marker; if it disappears evenly, the angle is right.
Leather stropping for a perfect finish
Stropping means drawing the blade over a strip of leather, after the stone or the steel, to polish the edge and remove the last micro-burrs. The movement goes in one direction only, spine first, never edge first into the leather, or you will cut it.
HORL sharpener: which model in the range to choose?
At HORL, the HORL 3 suits most kitchens, the HORL 3 Cruise tighter budgets, and the HORL 3 Pro enthusiasts who want more angles. The HORL 3 range succeeds the HORL 2 generation, which is still on sale.

Frequently asked questions
What is the best way to sharpen a knife?
A whetstone gives the finest edge and removes the least metal, but you have to learn to hold the angle. For a similar result with no learning curve, a rolling sharpener is the best compromise. Electric and pull-through sharpeners are the fastest, at the cost of more wear on the blade.
What is the difference between sharpening and honing a knife?
Sharpening reshapes the edge by removing metal, on a stone, a rolling sharpener or a machine, when the knife is dull. Honing realigns the edge, on a steel, between two sharpenings. In everyday speech, the two words are often used interchangeably.
How do you get a razor-sharp edge on a knife?
A razor edge needs a constant angle, a progression from medium to fine grit and a finish that removes the burr. On a stone, go from 1000 grit to 6000 grit, then finish on leather. On a rolling sharpener, finish with the finishing disc. Test it on a sheet of paper: it should slice through without catching.
How do you sharpen a Japanese knife?
A Japanese knife is sharpened at around 15 degrees, on a whetstone or on a sharpener that can be set to that angle, like the HORL 3. Avoid a steel honing rod, which is softer than many such blades, and sharpeners fixed at 20 degrees. For a single-bevel blade, follow the maker's instructions.
How do I know when my knife is sharp enough?
Colour the bevel with a marker before sharpening: when the mark has disappeared along the whole length, the metal has been removed evenly. A well-sharpened knife then slices a sheet of paper or the skin of a tomato without pressing.
