After decades of research the Japanese company Shapton has now optimised the grinding process with innovative ceramic sharpening stones. These achieve an exceptionally high level of material removal and thus save time when sharpening tools and knives. The ceramic sharpening particles are of high purity and homogeneity. This is noticeable when changing over to finer grits: the cutting traces from the previous grit are quickly ground out. The base of the sharpening stone is tempered glass and thus 100% warp-free.
A practical advantage: the grit rating on the underside is always visible thanks to the glass holder. Shapton ceramic stones are extremely long-lasting due to their wear resistance and need to be trued less often than conventional water stones.
