Abstract
A cutting blade for use in paper trimming machines and the like. A beveled surface is included which tapers the first side of the blade toward a second side so as to form an acute angle at the intersection of the second side and the beveled surface. The blade is regularly scalloped along the second side so that the scallops form an acute angle with the beveled surface. The generally serrated cutting edge so formed lies entirely within the plane of the beveled surface. During the cutting operation, the blade is inclined to the cutting plane so that the cutting plane and the plane of the beveled surface are substantially coincident. With the blade thus disposed, the cutting edges all lie within the cutting plane. Tearing and crushing of the paper is thus substantially avoided. The cutting edge so formed can be sharpened without significantly changing the shape of the cutting edge by grinding the beveled surface.
