The method used to form a particular type of blade. There are three basic types of grinds.
(1) Convex Grind – In cross section, the sides leading to the edge are rounded outward (convex). This grind is best in applications where heavy materials like wood need to be cut with a great deal of force.
(2) Flat (“V”) Grind – In cross section, the blade forms a “V” with straight sides. A compromise of convex and hollow grinds. May also be known as a straight grind.
(3) Hollow Grind – In cross section, the blade forms a concave shape with the sides hollowed out along the edge. Best suited for softer materials. Straight razors and many hunting knives are hollow grind.
