Why sharpening usually goes wrong

A sharp edge depends on holding one angle, stroke after stroke. On a stone that takes practice, and pull-through gadgets chew the edge. Here the block holds the angle for you.

Step 1

Set the knife on the block

The magnet holds the blade at 20° or 15°. Flip the block to choose.

Step 2

Roll the coarse side

Roll the 400-grit diamond disc back and forth along the edge, then turn the knife and repeat on the other side.

Step 3

Finish with the fine side

A few passes with the 1000-grit disc refine the edge. Wipe the blade and cook.

The angle is set for you

Most dull knives aren't worn out. The edge has rolled or chipped. Re-cutting it at a constant angle brings it back.

  • 20° for most kitchen knives: a sturdy, long-lasting edge.
  • 15° for thinner, harder blades, including many Japanese-style knives.
  • Non-slip feet keep the block steady on the counter.

Questions

How long does delivery take?

Orders ship from our fulfilment partner's warehouse with tracking. Most US orders arrive in 7–12 business days. You'll get a tracking number by email once your kit ships. See our shipping policy.

Will it work on my knives?

It works on straight-edged knives: chef's, santoku, paring, utility and most pocket knives, in stainless or carbon steel. It is not for serrated blades or scissors.

15° or 20°: which should I use?

Use 20° for most Western kitchen knives and everyday use. Use 15° for thin, hard Japanese-style blades, or if you know your knife has a 15° edge. If you're not sure, start with 20°.

Do I need water or oil?

No. The discs are used dry. Wipe the blade and the discs with a dry cloth when you're done.

Is it safe?

Your hand rolls the disc, not the blade, and the knife lies flat against the magnet. As with any sharpening, keep fingers away from the edge and store the kit away from children.
