Kasumi Combination Whetstone 600/1000 Grit, 185 x 62 x 24mm

The essential whetstone for kitchen knives. The 600 grit side reshapes a dull edge or fixes minor chips. The 1000 grit side sharpens it to a precise working sharpness ideal for both home and professional use. For most chefs, this is the only stone required: 600 to restore a worn knife, 1000 to maintain it.

Manufactured in Seki, Japan by Sumikama Cutlery, the parent company of Kasumi knives. Seki has been the hub of blade production in Japan for over 700 years, crafting samurai swords for centuries before shifting to kitchen cutlery. The same ceramic stone technology that maintains the sharpness of Sumikama's high-carbon VG-10 blades is utilized in this whetstone.

Designed for compatibility with all Japanese knives and also effective on European steel. The non-slip rubber base secures the stone firmly on the workbench during use. Packaged in a Kasumi gift box, it is ideal for home cooks establishing their first proper sharpening setup or as a present for someone who already owns knives but has been neglecting their sharpness.

How to use

• Soak the stone in water for 10 to 15 minutes prior to use, until no air bubbles are visible
