Coticule Stones

This particular type of whetstone is called a Coticule. They are characterized by a high concentration of spessartite garnets, have a characteristic white-yellow color, and are compared to water stones of 8,000 - 10,000 grit. They are fixed to a backing of blue-gray slate for stability. Coticules are somewhat brittle, and the slate backing prevents breakage. The slate is intended for structure only and is not used in the sharpening process.

Note that Coticules are hand shaped, natural stones. The presence of hairline fractures is normal and not considered a defect. Some variance of size, color and exact composition is also normal.
