Bernal Cutlery Takarazukushi 400 Grit Yellow Marble Hard Ceramic Japanese Whetstone

Bernal Cutlery Takarazukushi ceramic stones are made in Japan with alumina and zircon abrasive particles that are baked with ceramics creating a fused porous stone. Harder Takarazukushi stones tend to cut deeper and faster than the semi-soft stones on double bevel knives made with wear resistant steels. Semi-soft Takarazukushis stones cut wide bevels very nicely and leave shallower easier to finish scratches than the harder stones however both hard and semi-soft work on both.

Ceramic stones will not come apart with longer soaking periods (although water should be changed) resinoid stones should not be left to soak indefinitely, and both should be allowed to dry outside of sun and wind and not allowed to freeze wet.
