Abstract
A sharpener for sharpening a cutting tool having a blade portion with a cutting edge, such as but not limited to a kitchen knife. In some embodiments, the sharpener has first and second rollers, with the first roller rotatable about a first roller axis and the second roller rotatable about a second roller axis parallel to the first roller axis. An endless abrasive belt is arranged along a belt path that passes over the first and second rollers to define a planar segment that lies along a neutral plane from the first roller to the second roller. A guide assembly adjacent the planar segment of the belt is configured to contactingly engage the cutting edge of the cutting tool and apply a non-uniform surface pressure to a side of the cutting tool adjacent the cutting edge across a width of the belt.
