A filing guide for a saw chain having inner links with spaces therebetween, outer links and cutter teeth, the filing guide comprising a rigid body with a front edge shaped to abut against the inner links, a pair of spaced-apart elongated members extending from the body adjacent the front edge, the members being spaced-apart a distance approximately the same as the lengths of two of the inner links and the space therebetween, the body being shaped to glidably receive a round file, whereby a cutter tooth can be filed by the round file when the filing guide is positioned for use with the members inserted in the spaces between the inner links.

• and
• a filing guide for filing the cutter teeth of the saw chain comprising a rigid body with a front edge shaped to abut against the inner links, a pair of spaced-apart elongated members extending from the body adjacent the front edge, the members being spaced apart a distance approximately the same as the lengths of two of the inner links and the space therebetween, the body being shaped to glidably receive a round file, whereby a cutter tooth can be filed by the round file when the filing guide is positioned for use with the members inserted in the spaces between the inner links.
