Abstract
A machine for sharpening knives or similar cutting tools includes an endless abrasive belt and a tool engaging structure for supporting and guiding a tool into proper engagement with the belt. The tool engaging structure is located adjacent a portion of the belt path at which the belt is unsupported from behind so that as the tool is pushed against the belt the belt deflects inwardly. Damage to the tool and/or belt due to too large a force being applied between the tool and the belt is avoided by a pivotal unloader means which engages the tool and moves it away from the belt if an attempt is made to push the tool too far inwardly.
