A chain saw sharpener, having a fixture comprising a generally inverted U-shaped frame and a sharpening tool guide attached to a support bracket extending from the frame, which sharpening tool guide receives and guides a sharpening tool for use in sharpening the cutting links of a chain saw and is movable and may be set for sharpening of the cutting links at any angle specified by the chain saw manufacturer. The sharpening tool is a rotatable mandrel with a grinding stone at one end and structure at the opposite end for attachment to any suitable driving apparatus. A plastic shield protects the operator from being struck by metal fillings that are generated during the sharpening operation.
