Abstract:
In the process of a saw tooth with a sharp forward positioned cutting edge advancing into the material addressed with a scratch scrape action, the improvement wherein the side of the tooth having a bevel edged flat surfaced protrusion distinct from said tooth's cutting edge, withsaid protrusion projecting slightly further laterally from the center plane of the saw blade than a most lateral projection of the sharp forward positioned cutting edge, with said protrusion projecting laterally far enough for its surface of engagement, wherein said protrusion has a working surface, to generate a rubbing action against the kerf surface that has been freshly cut by the forward positioned cutting edge of the saw tooth, but not projecting far enough laterally to cut into the kerf, with said rubbing action of said protrusion's working surface generating pressure, friction, and friction-generated heat, against said kerf surface, whereby said protrusion serves as a finishing element rendering said kerf surface smoother, flatter, and denser.
