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.

A chip removing cutter blade for use in metal working comprising a monolithic body of molded metal cutting material with a plurality of deep material saving recesses molded therein, a substantially flat base, a wall extending from a side of said base, a plurality of spaced abutments interconnecting the wall and said base;
- said base, the wall and said plurality of abutments defining said plurality of deep material saving recesses;
- an outside of said wall ground to the desired cutting contour for said cutting blade, and the top of said wall ground to produce a cutting face, the intersection of said cutting face and the contoured outside of said wall creating a cutting edge.
