ABSTRACT:
A precision file for sharpening saw teeth. The file includes a flattened oblong cross section for exact shaping of the saw teeth. Two sets of single cut teeth are cut into the file and extend over the file's longitudinal axis. A first set of teeth extends from a central lateral axis outward toward one end of the file, and a second set extends from the central axis outward towards the file's second end. The file is thus capable of an extensor cutting stroke using either end.
