How to use it
How to use it
- Stick the knife flat to the magnet, edge up, on the 20° side (15° for Japanese knives).
- Roll the diamond disc along the edge about twenty times.
- Turn the knife over and repeat on the other side.
- Swap to the ceramic disc: ten rolls a side.
- Chef's Kit: finish with five or six passes a side on the strop, spine first.
Hold the roller, not the knife, and keep your fingers away from the edge.

Care and safety
Care and safety
Wipe the discs with a damp cloth after use and let them dry. Don't soak the wooden roller or put it in the dishwasher. The magnets are strong: keep them away from bank cards and pacemakers. Keep out of reach of children.
The tomato test
It's the first thing you'll try. Take a ripe tomato and don't press: let the weight of the knife do the work. Blunt, the skin dents and splits. Sharp, the knife drops straight through.

Before you buy
What does it sharpen?
Chef's knives, santokus, paring, utility and carving knives, in stainless or carbon steel, European or Japanese double-bevel.
What doesn't it sharpen?
Serrated bread knives, scissors, ceramic knives and single-bevel Japanese knives.
Will it damage my knives?
No. The magnet holds the angle steady and the diamond disc takes off only as much metal as it needs. Pull-through sharpeners remove far more.
Where does it ship from?
From our manufacturing partner's warehouse outside the UK. All taxes are included in the price, so there's nothing to pay on delivery.
Can I change my mind?
Yes. You have 14 days from delivery to cancel for any reason, and we'll refund you in full without asking for the kit back.
