Shapton Pro 320 Ceramic Whetstone
The Shapton Pro series are fast cutting hard stones that work very well on wear resistant steels. This 320 grit stone is a coarse cutting stone, for shaping and removing chips and damage. A medium and fine stone should be used after use to refine the edge. Flatten with a coarse flattening plate often.
Does not require soaking, simply splash with water and go.
