ABSTRACT:
A saw chain includes a non-cutting guard link having a base with rivet-receiving openings, and a top portion with a nose extending rearward of the base portion. The nose is formed by coining, rolling, or bending, such as in a progressive die system, so that the width of the nose is approximately equal to the width of the base portion of the guard link plus the width of a center link to which the guard link is pivotally connected. Right-hand and left-hand cutter links follow, respectively, left-hand and right-hand guard links, the guard links cooperating with the cutter link depth gauges to present a facial area approximately equal to the chain width to thereby minimize kick-back.
