Abstract SAW CHAIN USING AN IMPROVED SIDE CUTTER TOOTH To provide better performance for a saw chain by enhancing the life and performance of side cutter teeth, this invention discloses a novel side cutter tooth which includes a cutter element having either a continuously curved portion attached to the body of the cutter tooth or a substantially straight portion extending outwardly from the body of the tooth. The continuously curved portion or substantially straight portion causes the cutter element to bend substantially at the intersection between the body and the cutter element when the cutter element is exposed to inwardly directed forces which tend to flatten the curved or substantially straight portion out of its half-space into the plane defined by the body of the cutter tooth. Removal of the complex curve ordinarily used in the center-mounted cutting teeth of saw chain greatly enhances the performance of the cutting teeth, reduces breakage of the teeth, and improves the efficiency of a saw chain using the improved cutting teeth.
