Abstract
Apparatus for sharpening a cutting tool. In some embodiments, a tool sharpener includes an abrasive medium having an abrasive surface. A stationary tool support guide provides a guide surface that supports a side of the tool during presentation of a cutting edge of the tool against the abrasive surface. A rotatable edge guide has a roller member with a curvilinearly extending outer surface. The roller member is rotatable about an edge guide roller axis and is moveable between a deployed position and a retracted position. In the deployed position, the roller member is positioned to engage, via rolling contact, the cutting edge during the presentation of the cutting edge against the abrasive surface. In the retracted position, the roller member is positioned to provide a non-contacting clearing relation with the cutting edge during said presentation.
