Abstract

A protrusion on the side of the saw tooth rubs against the newly cut kerf surface as the tooth cuts. Pressure, friction and friction-generated heat are produced through this rubbing action. The confluence of this pressure, friction, and heat, performs a polishing action against the newly cut kerf surface.

Claims

1. A saw tooth, the improvement wherein said tooth having a lateral protrusion on the side of the tooth nearest the kerf,

wherein the protrusion projects slightly further laterally from the center plane of the saw blade than the most lateral projection of the cutting edge of the saw tooth,

wherein as the tooth performs its cutting action the lateral protrusion rubs against the newly cut kerf surface,

whereby, a polishing action is performed on said surface.

2. The protrusion of claim 1 with the design of the protrusion and its surface of engagement chosen from a plurality of design characteristics relating to composition.

3. The protrusion of claim 1 with the design of the protrusion and its surface of engagement chosen from a plurality of design characteristics relating to configuration.

4. The protrusion of claim 1 with the design of the protrusion and its surface of engagement chosen from a plurality of design characteristics relating to texture.

5. The protrusion of claim 1 with the design of the protrusion and its surface of engagement chosen from a plurality of design characteristics relating to location.
