Hatori Diamond Rolling Knife Sharpener™

The Hatori Diamond Rolling Knife Sharpener is a leather roller that sharpens by rolling. Hold the knife on the magnetic block, roll along the blade, and the edge is sharp in about 30 seconds. A diamond disc sits on one end of the roller and a honing disc on the other. The magnetic block holds your knife at a steady 15° or 20°, so every pass lands at the same angle. Two discs, Arato and Nakato, come with it. It is the heart of Togi 砥, the Hatori sharpening system. Use it on every kitchen knife you own. It comes in a gift box, with free shipping and a 60-day money-back guarantee.
