A tool for sharpening ice-skates is disclosed. The tool is hand-held, and uses a magnet to hold the cutting surface against the skate blade. The cutting face of the tool is convexly curved to fit the hollow portion of the blade. A liner, impregnated with abrasive dust, may be interposed between the magnet and the blade. The liner may be removed, and the magnet rubbed directly against the blade for final, fine sharpening. A cover for the magnet includes a safety guard and a gripping aid.
