Razor-Sharp Knives Without Guessing the Angle
Blunt knives squash tomatoes, slip off onions and make cooking a chore. Whetstones need years of practice to hold the right angle, and pull-through sharpeners can chip a good blade. This rolling sharpener takes the guesswork away: the magnetic block holds your knife at a fixed angle and you simply roll the sharpener along the edge.

Why most knives in the drawer are blunt
How it works
Sharp in three simple steps
1. Attach the knife to the magnetic block
Choose the 15° or 20° side and lay the blade against it. The magnets hold the knife firmly at that angle.
2. Roll the sharpener along the blade
Roll back and forth with light pressure; the weight of your hand is enough. Start with the diamond disc to sharpen, then turn the roller round and use the ceramic disc to polish the edge.
3. Slice with ease
Turn the knife over, repeat on the other side, and the edge is ready. Most knives take about a minute.
Two discs in one roller
Diamond to sharpen, ceramic to polish
One end of the roller carries a diamond-coated disc. Diamond is the hardest abrasive there is, so it quickly takes off the dull layer of the edge and sets a new one.
The other end has a ceramic disc for the finishing pass. It smooths and polishes the fresh edge, so the knife glides through food.
The roller has a steel core, so it feels solid in the hand and rolls evenly.
Safe for your knives
The angle is set, so the edge stays even
Ever had a sharpener that chipped or ruined a good knife? The magnetic block locks the blade at the exact same angle every time, so you get a clean, even edge without grinding away more steel than needed.
That makes it suitable for everything from an everyday supermarket knife to a good Japanese blade.
- 20° side: for Western and most everyday kitchen knives.
- 15° side: for Japanese knives with a finer edge.
- Not sure? Use 20°.
- Strong neodymium magnets: hold the blade steady while you roll.
Works on your knives
For almost every straight-edge knife
Chef's knives, santoku, paring knives, cleavers, filleting, hunting and pocket knives: if the edge is straight, you can sharpen it.
It is not made for serrated bread knives or scissors.

Questions people ask
Will it work on my knives?
Yes, on any straight-edge knife: chef's, santoku, paring, cleaver, fillet, hunting and pocket knives. Not on serrated bread knives or scissors.
Which angle should I use?
20° for Western and supermarket knives, 15° for Japanese knives. If you are unsure, choose 20°.
How much pressure do I need?
Very little. Let the weight of your hand do the work.
How long does the diamond disc last?
More than 1,000 knives in a home kitchen. After that, a replacement disc clicks in.
Will it scratch or damage my knife?
The magnetic block holds the blade at a fixed angle, so the discs only touch the edge and grind it evenly.
