ABSTRACT:
A file guide device for use in guiding a file in the operation of sharpening the teeth of saws and the like is disclosed. The device comprises a support member adapted to be fitted to a saw in a predetermined relation to the teeth thereof and a carrier member mounted to the support member for rotatably supporting a pair of rollers for guiding the file along axes corresponding to the angles of the cutting edges of the saw teeth. In one embodiment, the axes of the rollers are arranged in a fixed location with respect to the support member and are arranged so that the roller rotation plane is substantially horizontal. In another embodiment, one roller is movably mounted relative to the support member and is resiliently biased in a direction to move the file axis toward the cutting edge of a saw tooth.
