ABSTRACT:
A saw blade has a series of triangular saw teeth, each tooth having a cutting edge and back edge joined by a tip edge with a cutting angle tapered rearwardly from the front cutting edge. The cutting angles of the cutting edges are progressively reduced from the leading end to the trailing end. Additionally, the teeth may be formed of a combination of laterally projected teeth and straight teeth.
