Abstract
A faster more efficient cutter link for a saw chain is provided by contouring the toe portion to have several cutting edges spaced apart by non-cutting areas so that smaller chips are formed which can be more easily broken up and moved from the saw kerf. The cutting surfaces can be arcuate or linear and can extend all the way across the saw kerf or only part way, depending upon the particular configuration desired.
