Description

The hard bond is preferable for high-alloy tool steels. Coarse-grained alloy constituents of tool steels (e.g. chromium and vanadium) require a stone that wears slowly.

Glass Stones by Shapton^®

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.
