Grind Wikipedia

A blade''s grind is its crosssectional shape in a plane normal to the edge. Grind differs from blade profile, which is the blade''s crosssectional shape in the plane containing the blade''s edge and the centre contour of the blade''s back.. Grinding is the process of creating grinds. It involves removing significant portions of material from a blade, which distinguishes it from honing and polishing.
