Claim:
A saw blade comprising: a flat, circular disc having a peripheral outer edge and a center hole; a plurality of circumferentially-spaced teeth each having a substantially axially extending cutting edge and projecting radially outwardly from the peripheral outer edge; a first group of the cutting edges defining a first circumferential width between each adjacent pair of the cutting edges in the first group; a second group of the cutting edges defining a second circumferential width between each adjacent pair of the cutting edges in the second group; the second circumferential width differing from the first circumferential width; at least one of the first and second groups including at least three of the cutting edges; and a third group of the cutting edges having at least one of the cutting edges defining a third circumferential width as one of the distance between adjacent cutting edges in the third group and, the distance between the at least one cutting edge in the third group and the adjacent cutting edge in the adjacent group; the third circumferential width differing from the first and second circumferential widths.
