Abstract
Various embodiments of the present invention are generally directed to an apparatus for sharpening a cutting tool. A tensioner assembly applies a biasing force to a roller to maintain a selected tension in a belt and to facilitate translational displacement of the roller during deflection of the belt. In some embodiments, the tensioner assembly includes a shaft with an L-shaped groove with an elongated portion and an offset portion to facilitate transition of the roller between an extended position and a retracted position. In related embodiments, the tensioner assembly comprises a shaft with an elongated groove to facilitate tracking alignment of the belt on the roller. In further related embodiments, a guide housing is provided adjacent an abrasive medium with a guide slot and magnet to facilitate presentation of a cutting tool against the abrasive medium.
