ABSTRACT:
A device for controlling filing of a depth gauge of a saw chain has an elongated file holder with a center portion having clips for holding a file. The filing surface of the file faces outwardly from the holder. The file holder has a flat surface facing outwardly on a first side of the center portion and has a straight edge facing outwardly on a second side of the center portion. The flat surface and the straight edge are positioned relative to the center portion such that, after a depth gauge of a first cutter link has been filed to a desired level, the flat surface rests against the cutter edge of the first cutter link while the straight edge engages the non-cutter link of the chain and a back of a second cutter link.
