Abstract
Apparatus for sharpening a cutting tool. In some embodiments, a tool sharpener is provided with a flexible abrasive medium having an abrasive surface and arranged along a planar extent. A guide assembly has a guide frame, a cam surface, and a pivotal guide member. A guide surface on the guide member extends at a selected angle with respect to the planar extent of the medium to support a first side of the tool during presentation of a second side and cutting edge of the tool against the abrasive surface along the planar extent. A cam follower contactingly engages the cam surface to establish the selected angle. A biasing mechanism applies a biasing force to urge the guide surface to pivot toward the planar extent to maintain the cam follower in contact with the cam surface.
