Abstract
Apparatus and method for sharpening cutting tools. In accordance with some embodiments, an abrasive medium is presented adjacent a guide housing. The guide housing includes a guide slot to facilitate presentation of a magnetically permeable tool against the abrasive medium. A magnet positioned adjacent the guide slot exerts a biasing force upon the tool that both draws the first tool against a guide surface of the guide slot and draws the tool into the guide slot along the guide surface to hold the tool at a neutral position at which a cutting edge of the first tool applies a contacting force against the abrasive medium.
