<p>A device for controlling filing of a depth of a saw chain has an elongated file holder with a centre 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 centre portion and has a straight edge facing outwardly on a second side of the centre portion. The flat surface and the straight edge are positioned relative to the centre 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. </p> |
