Best Knife Sharpeners for Beginners

Buy the Tumbler rolling sharpener. It is two pieces — a magnetic holder and a rolling abrasive disc — and it fixes your angle at 15 or 20 degrees so you physically cannot get it wrong. Three minutes a knife, nothing to set up, and 15 degrees happens to be the correct angle for most Japanese kitchen knives. If you would rather learn the skill than buy around it, skip to the King stone.

Beginners do not fail at sharpening because they lack abrasive. They fail because sixty strokes at a consistent 15 degrees is a motor skill, and on stroke forty the spine drifts up two degrees and the bevel rounds over. Every tool on this page is a different answer to that one problem: remove the variable mechanically, constrain it with a clamp, or learn to feel it.

1. A fixed or guided angle. Not a suggestion, a mechanism. A magnetic roller or a clamped rod gives you the same angle on stroke sixty as on stroke one. This is the single feature that separates a good first sharpener from a bad one.
2. 15 degrees per side, available. Japanese kitchen knives come from the factory between about 15 and 16 degrees per side. A tool that only offers 20 degrees will grind a new, blunter edge onto your knife and it will take several sessions to undo. Our angle chart has the numbers by knife type.
3. Abrasive that is replaceable, not disposable. Rolling sharpeners with removable discs and guided systems with separate plates can be serviced. A sealed pull-through with fixed carbides is worn out when it is worn out, and it scrapes steel off in strips in the meantime — see why we do not recommend them.

The Work Sharp is the most capable tool here and the one most likely to sit in a cupboard. It adjusts in one-degree increments from 15 to 30, comes with five diamond plates, a ceramic and a strop, and it will put a better edge on a knife than a roller can. It also has a clamp that fights a 240 mm gyuto and a lot of parts to lay out. Buy it if you have four or five knives to do in one sitting.

• You want a sharp knife and no project. Tumbler rolling sharpener. Magnetic holder, 15-degree setting, two pieces. In side-by-side comparisons it produces an edge as sharp as the German alternative at a considerably lower price.
• You have several knives and want one setup to do them all. Work Sharp Precision Adjust Elite. One-degree angle increments mean you can actually match a 15-degree Japanese factory edge, and the seven abrasive options cover chip repair through polish.
• You want the skill, not the shortcut. King KDS #1000/#6000. The soft clay binder gives feedback no fixed-angle device can, it removes the least steel of anything here, and it follows whatever grind is already on the blade. Expect the first attempt to be disappointing.
• Whatever you chose above. Idahone 12 inch fine ceramic rod. It is harder than a 60 HRC Japanese blade, where a ribbed steel rod frequently is not, and thirty seconds every few uses keeps an edge feeling fresh for weeks longer.

A roller first, because it works immediately and costs little. A honing rod alongside it within a month, because the roller fixes the edge and the rod keeps it. Then, about a year later, a 1000-grit stone — bought not because the roller failed but because the roller only does 15 and 20 degrees, and by then you want to thin a blade behind the edge or fix a chip or follow an asymmetric grind. That progression costs more in total than buying the stone on day one, and far more people finish it.

If you already know you are the sort of person who will enjoy the stone, start there and save the detour: the beginner whetstone picks cover which 1000-grit stone suits the steel you own, and are whetstones worth it is the honest case both ways.

Tumbler for the beginner who wants a result tonight. Work Sharp Precision Adjust Elite for the beginner with a drawer of knives and an afternoon. King KDS for the beginner who wants to be able to sharpen anything in ten years' time. An Idahone ceramic rod in all three cases, because honing is the cheapest sharpness per dollar in this whole category.
