Crystolon Combination Benchstone Coarse/Fine

This is a 4" round combination Crystolon, or silicon carbide, stone with both coarse and fine sides. The coarse side is very aggressive and is used for bringing dull edges back to sharpness. The fine side is used to restore edges that are slightly dull, and for refining the edge left by the coarse side.
