In a chainsaw sharpener, a round shaft-shaped grinding tool is attached to an end of a drive shaft of a handy type electric motor. Mounted on and forward of the electric motor of a sharpener body via a mounting portion is a guide body having, formed therein, an upper plate face and wall faces which have a substantial X-shape as seen in plan view, extending in two directions, and which are fit into and along an upper part of the saw chain in alignment with a sharpening angle of either a left or right cutter blade of a saw chain. Formed at a substantially central surface of the guide body is an exposure portion made of openings and a cutting edge of a cutter blade to be sharpened. A guide portion for pressing, from above, the cutter blade to be sharpened is also provided.
