<p>FILING GUIDE A filing guide for saw chain which includes a plate having a flat expanse joining with a curved expanse at the forward end of the guide which forms a cylinder. The guide is usable, with one side facing upwardly and the cylinder seated in a pocket defined in a saw chain, to guide a file during filing of a depth gauge and a safety projection in the saw chain. With the guide turned over from this position, and the cylinder again seated in the pocket, the guide is useable to guide a file during filing of a cutting edge in the saw chain.</p> |
