Kasumi Marble Whetstone 1200 Grit, 185 x 62 x 24mm

This is a versatile whetstone designed for kitchen knives that have begun to dull. With a grit of 1200, it falls between coarse repair stones and fine finishing stones, making it ideal for regular sharpening without excessive material removal. Use it to restore a knife that has become dull from frequent use, or as part of a multi-stage sharpening process.

Manufactured in Seki, Japan by Sumikama Cutlery, the same company that produces Kasumi knives. Seki has been a hub for blade craftsmanship for over 700 years, and this stone utilizes the same ceramic technology that maintains Sumikama's high-carbon VG-10 blades.

The stone's marbled appearance gives it its name and distinguishes it from the standard Kasumi line. It is suitable for all kitchen knives, both Japanese and European, including harder Japanese steels that require a ceramic stone instead of a softer natural one. The non-slip rubber base keeps the stone stable on your work surface while sharpening. It comes packaged in a Kasumi gift box.

For knives that are significantly dull or have chips, begin with a coarser stone like the Kasumi 600/1000 Combination. To achieve a mirror-polish finish after using this stone, follow up with the Kasumi Marble 2000 or a higher grit stone.

How to use

• Position on the rubber base on a stable surface
• Hold the blade at a 15 to 20 degree angle and sharpen each side evenly with light pressure
