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.

This semi soft Takarazukushi stone tends to cut deeper and faster than the other semi-soft stones, it is a very wide ranging stone doing great on double bevel knives made with wear resistant steels as well as providing a great abrasive rich fast cutting mud ideal for wide bevel and single bevel knives.

Ceramic stones will not come apart with longer soaking periods (although water should be changed) resinoid and magnesia bonded 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.
