Abstract
Apparatus and method for sharpening a cutting tool having a cutting edge. In some embodiments, a manual sharpener includes a base housing adapted to be contactingly supported on a base surface, with the base housing having an overall length dimension in a first direction. A support member extends along the overall length dimension of the base housing and is adapted for rotation with respect to the base housing about a central axis extending along the first direction. An abrasive surface covers a top surface of the support member. The support member rotates the abrasive surface responsive to presentation of the cutting edge of the tool thereagainst as the cutting edge is moved along the abrasive surface in the first direction. A biasing mechanism coupled to the support member urges the support member to a neutral rotational position with respect to the base housing.
