Abstract
A blade sharpening apparatus comprising a rotor, including a plurality of interleaved fingers, operative to interface with the cutting edge of a blade. The rotor is coupled to a rotary drive, such as an electric motor, thereby automating the sharpening process. Preferably, each of the fingers is flexible and includes a lead-in in the form of a radius or chamfer to prevent kick back from the heel of the blade or knife being sharpened. It is also preferable that the sharpening fingers include a portion of abrasive material or surface treatment.
