What cooks are saying
How it works
The only skill in sharpening is holding one exact angle. The magnet holds it for you.
1 — Attach
Set your knife against the block — the magnet pulls the blade flush at the exact angle, 15° or 20°.
2 — Roll
Roll along the edge with light, even pressure. The coarse disc restores the edge; the fine disc finishes it.
3 — Test
Slice a tomato. If the skin gives with no sawing, you're done — a weekly touch-up takes under a minute.

Frequently asked questions
Will it work on MY knives?
Will it work on MY knives?
If it's a straight-edge, double-bevel steel knife, yes — that's most kitchen and pocket knives: chef's, santoku, gyuto, paring, utility, boning. Use the 20° face for Western steel, the 15° for Japanese double-bevel. It won't do serrated, ceramic, or single-bevel blades (yanagiba, deba, usuba) — we'd rather say so than sell you the wrong thing.
I've genuinely never sharpened a knife. Can I do this?
I've genuinely never sharpened a knife. Can I do this?
Yes — that's who it's built for. The magnetic block holds the angle, which is the one part that used to take skill. You roll with light, even pressure. If you can use a rolling pin, you can use this. A few minutes brings back a neglected knife; a weekly touch-up takes under a minute.
Is this like the pull-through sharpener that wrecked my last knives?
Is this like the pull-through sharpener that wrecked my last knives?
Different mechanism. A pull-through drags your edge through a fixed carbide notch under tension — which is the design behind most of those wrecked-knife stories. Willow & Stone never puts your edge through a notch at all: the knife rests at a set angle on a magnetic block while a diamond disc rolls across the edge. The angle is fixed by the tool, not scraped by a slot.
Will it damage or over-grind my good knives?
Will it damage or over-grind my good knives?
The angle is held on a fixed face, so it doesn't wander into your edge the way freehand mistakes or a sloppy gadget can. Use light, even pressure — that's the one habit to keep. Independent reviewers testing this kind of rolling sharpener found the preset angles close enough to factory edges to enhance them, not ruin them.

Reviews
The results are without a doubt the best I have ever achieved at home… I could not be happier.
I tested it out on a crap knife I keep around and it was tomato slicing sharp after using this. So far, so good.
…in 2 minutes… without any practice or prep…. THIS is the product I recommend.
This little gadget makes knives insanely sharp with very minimal effort.
I have sharpened my Damascus steel knives and German knives to razor sharpness with ease.
Very simple and consistent, and because it’s so easy I find myself sharpening and touching up the edge of my knives more frequently.
They absolutely are worth it. You pull them out and sharpen your knife. No soaking, no oiling, just sharpening. I recommend them to all cooks.
It works well with most knives and doesn’t require training or skills.
If you can stick a knife to a magnet and keep your hand away from the blade, you can use one of these sharpeners.
Something I would definitely be happy sitting on my kitchen work surface rather than shoved away in a drawer.
Easy to use, and it does work… I am a satisfied customer.
It’s so good and so easy that even I can get my knives nice and sharp!
Stop sawing at dinner
It was never you — it was the angle. And the angle is the one thing Willow & Stone holds for you.
