A universal sharpening apparatus for sharpening a tool includes a grinding wheel assembly (14) and a universal clamping system (18) for clamping the tool rigidly in any of a wide range of spatial relations to the grinding wheel. The universal clamping system includes two arcuate bearings (20, 22) each having an effective axis of rotation. The arcuate bearings are mechanically interconnected so as to be deployable with their respective axes of rotation parallel such that opposing rotation of the arcuate bearings generates a non-rotational displacement of the tool relative to the grinding wheel. |
