Abstract
A circular saw blade having an inner drive portion, an outer cutting edge portion, and a plurality of angled slots extending through the blade from the first lateral surface through to the second lateral surface of the blade. The angled slots are radially spaced inboard of the outer cutting edge portion and they are closed and thus do not open to the outer diameter of the saw blade. The angled slots serve to produce an audible signal in the event the saw blade is rotated in the wrong direction of rotation upon a drive unit.
