Shapton

The Japanese sharpening stone manufacturer Shapton^® from Nabatame, Tochigi Province, produces probably the hardest Japanese water stones. In contrast to almost all other makes, they keep their shape longer and require less frequent dressing.

The premium range from Japanese company Shapton^® is the glass-stone series. The sharpening particles are highly pure and homogeneous. This is noticeable when changing to finer grits: The traces from the previous grit are quickly ground out. A special bond allows quick sharpening on a flat surface. The sharpening stone has a base of tempered glass and is thus 100 % warp-free. Conventional sharpening stones may warp microscopically by absorbing water, but Shapton^® stones solve this problem with their extremely flat base of tempered glass. Another advantage of the glass base is that the grit rating on the underside is always visible even after much use. Before use, spray the stones with water. It is not recommended to keep them in water permanently. White aluminium oxide abrasive.
