ABSTRACT:
A saw blade comprises scratcher teeth which are not set, and shaving teeth which are set. All of the teeth have their leading and trailing lateral edges chamfered. The chamfering of successive teeth occurs at alternate sides of the blade. The scratcher teeth have sharp points, whereas the shaving teeth are truncated to form oblique top surfaces and to render the shaving teeth shorter than the scratcher teeth.
