Abstract
A blade sharpener for a pocket knife is in the form of an appendage which can be removably secured to the knife handle and which carries a superabrasive layer sharpening surface, such as an electroplated diamond grit. The appendage may take the form of a pair of tweezers, such as those commonly found on Swiss army type knives, with the superabrasive layer being attached to its inside surfaces.
