Spare and extra stones for the Fixed-Angle Knife Sharpener. Each one is a thin diamond-coated plate on a black base, and it fits in the stone holder of the sharpener.
Work from coarse to fine. A low grit brings back a blunt or chipped edge. The higher grits refine it and leave a smooth, polished finish. Diamond cuts steel quickly and stays flat, so the stones never need flattening.
In each pack: Pack of 4: 300, 800, 1600 and 3000 grit. Pack of 6: 150, 600, 800, 1200, 2000 and 3000 grit. Pack of 8: 180, 240, 400, 600, 800, 1000, 2000 and 3000 grit. The grit is printed on each stone.
Good to know: they can be used dry or with a little water. Rinse and dry them after use. The sharpener is sold separately.
Delivery: free to UK addresses, in 7 to 10 working days. Delivery details.
Returns: you have 30 days from delivery to send it back, unused. Returns and refunds.
Guarantee: 2 years, in addition to your statutory rights.
1. Clamp the knife in the sharpener and set the angle.
2. Fit the coarsest stone you need in the stone holder. Start low only if the edge is blunt or chipped.
3. Draw the stone along the edge, from heel to tip, with light, even pressure, until you feel a slight burr along the other side.
4. Turn the knife over and sharpen the second side the same way.
5. Move up one stone at a time, with lighter pressure on each finer grit.
6. Rinse the stones, wipe them dry and keep them in order.

Coarse to fine
Each grit has one job. Start low to bring a blunt edge back, then move up the stones to refine and polish it.

The grits
The lower the number, the coarser the stone. 300 grit brings back a blunt edge. 800 grit sharpens it. 1600 and 3000 grit refine and polish it. The packs of 6 and 8 add more steps along the way.

Diamond

Three packs
They are made for the Honvik Fixed-Angle Knife Sharpener and fit its stone holder. For another guided system, check the length and width of its stones before you order, or write to us.
The pack of 4 covers every step, from a blunt edge to a polished one. The packs of 6 and 8 add more grits in between, for smaller steps and a finer finish.
Start on the coarsest stone only if the edge is blunt or chipped. For a knife that is only a little blunt, start in the middle of the range, then finish on the finest stone.
No oil. Diamond stones work dry, or with a little water. Rinse them after use and let them dry.
No. A diamond plate stays flat, so it never needs flattening.
Delivery is free in the UK and takes 7 to 10 working days. If you change your mind, you have 30 days to send it back unused, and it comes with a 2-year guarantee.
