ABSTRACT:
A visual guide for sharpening chain saw teeth. Magnetic material is affixed to one leg of an elongated member having an L-shaped cross section. The magnetic material is affixed to the external portion of the leg such that when the device is magnetically attached to a chain saw blade, the other leg of the device will extend away from and parallel to the chain saw blade. Markings are formed on the upward-facing portion of the second leg indicating the correct angle for applying a circular file to the cutting edge of the chain saw tooth. Notches are formed on the device for use as a template in gauging the proper shape of the chain saw tooth being filed.
