Abstract:
1. A sharpening apparatus comprising a flexible abrasive belt extending along a first plane and a guide housing, the guide housing comprising a guide slot having stationary first and second guide surfaces in respective facing relation and which converge to an edge guide surface at a distal extent of the guide slot, the guide slot further having a proximal open end opposite the edge guide surface to facilitate presentation of a magnetically permeable tool into the guide slot and against the flexible abrasive belt, the sharpening apparatus further comprising a magnet positioned adjacent the guide slot to exert a biasing force upon the tool that both draws the tool against the first guide surface of the guide slot and draws the tool into the guide slot along the first guide surface to hold the tool at a neutral position at which a cutting edge of the tool applies a contacting force against the flexible abrasive belt sufficient to deflect the abrasive belt out of the first plane, the first guide surface extending along a second plane that intersects the first plane along an intersection line that extends between the open end of the guide slot and a distal edge of the magnet proximate the edge guide surface of the guide slot.
