Abstract
A cutter blade for use in cutting metal is formed with a recess spaced behind the cutting edge on the cutting face to save expensive cutting material, to reduce the time and energy required to sharpen the cutter blade, and to lengthen the life of the sharpening tool. High density sintered powdered tool steel lends itself well to this construction, as do cast and forged tool steels.
