ABSTRACT:
A self-guiding circular saw, the saw having a series of circumferentially spaced teeth around the periphery thereof. A pair of ribs protrude on opposite sides of the saw blade with each rib being co-extensive with the other and extending from the periphery of the blade linearly toward the central area of the blade. The combined thickness of the ribs and the blade being greater than the thickness of the blade but less than the kerf defined by the teeth of the saw such that the ribs will function to guide the saw in a straight path in the cut.
