This silicon carbide Crystolon bench stone provides both a coarse and a fine cutting surface. Allows fast cutting for general sharpening of cutting tools.  Ideal for carbide-heavy tool steel, such as M2 or the CPMs.

All Crystolon Stones are made of silicon carbide electric furnace abrasive. Electric furnace stones are made by ball-milling the abrasive to the correct particle size, then batch-blending with carefully selected bonding agents to produce the precise characteristics desired in the finishing stone.  This produces a fast-cutting abrasive which is harder than any natural abrasive except diamond and does an outstanding job where moderate tolerances are desired. The resulting tool edge lacks durability as compared to India. Crystolon is the choice when speed of sharpening is more important than fineness of the cutting edge. Dark gray in color. Stone measures 6"L x 2"W x 1"H.  Made in Mexico.
