ABSTRACT:
A clamp for sharpening chain saws does not require removal of the saw chain from the saw prior to the sharpening operation. The clamp comprises a supportive backing plate, a threaded member for fixing the saw blade into position relative to the plate, and a stop for preventing movement of the saw chain teeth along the saw blade during the sharpening operation. Preferably, the stop comprises a pivotable arm which is engageable with any one of the saw teeth.
