ABSTRACT:
A sharpener for manual sharpening of the cutting teeth of saw chains for chain saws having a depth limiter disposed in front of the cutter in the cutting direction for controlling the depth of the cut. The cutter is defined by the line passing through a free surface forming the back of the teeth and a cutting face situated on the front of the teeth. A round file is provided for sharpening the cutter by cutting processing of the cutting face. The file is adapted to the tooth front with the cutting face in cross-section. Parallel to the round file, are positioned a guiding rod, which can be placed on the free surface of a cutting tooth to be sharpened, a guiding rod, which can be placed on the free surface of an adjacent cutting tooth, and a second file which can be placed on the depth limiter of the cutting tooth to be sharpened. The two guiding rods, the round file and the second file with respect to each other corresponds to the geometry of the cutting teeth.
