ABSTRACT:
A saw has a plurality of generally V-shaped teeth formed by punching. The sides of each tooth define cutting edges. A bevel extends along each cutting edge. The bevels are formed by punching with a tool having a surface oriented non-perpendicular to the saw blank. Burrs formed during the punching step are not removed, but are allowed to remain to enhance the cutting ability of the teeth.
