Find your angle
Five angles. Every knife you own.
Each side of the magnetic block holds the blade at a different angle. Pick the one that matches your knife and the magnet does the rest.

How it works
Fix. Grind. Hone.
Three moves, a few minutes, and the same angle on every pass.
STEP 02
Grind
Roll the diamond disc along the edge, heel to tip. Flip the knife and repeat on the other side.
STEP 03
Hone
Switch to the honing disc and finish with a few light passes to refine the edge.
Why rolling
Whetstone results, without the learning curve.
How a magnetic rolling sharpener stacks up against the two usual options.
| Feature | SharpOX rolling | Pull-through | Whetstone |
|---|---|---|---|
| Consistent angle | Magnet-locked | Fixed slot | Depends on skill |
| Angle options | 5 angles | Usually 1 | Any, by hand |
| Learning curve | Minutes | None | Practice needed |
| Control over metal removed | Light, even passes | Can be aggressive | High, with skill |
| Setup and mess | None | None | Water and soaking |
General comparison of sharpening methods. Results depend on the knife and its condition.

Which angle should I use?
If you know your knife's factory angle, match it. As a guide: thin Japanese-style blades usually suit 12–15°, most everyday Western kitchen knives suit 17–19°, and thick or heavy-duty blades suit 22°. Not sure? Start at 19° for an everyday chef's knife.
Does it work on serrated knives?
No. It's made for straight-edge blades. Serrated knives need a tapered rod that fits each scallop.
Will it wear my knives down?
Any sharpener removes a little metal. Use the matching angle, light pressure and a few passes, and only grind when the knife is dull. Between sharpenings, a few passes on the honing disc keep the edge fresh.
How long does it take?
A dull knife takes a few minutes. Regular touch-ups are quicker.
Can I use it on ceramic knives?
We recommend it for steel blades only.
How do I care for it?
Wipe the discs with a damp cloth and dry them. Keep the magnetic block away from bank cards and other magnetic-stripe items.
