ABSTRACT:
Various forms of knife guides are provided for knife sharpeners to minimize damage to the knife blade. The knife guides include the provision of flexible fibers on the guide surface and further include rings, such as O-rings on an array of rollers when the rollers are used to form the guide surface. Other forms of knife guides are non-contact optical arrangements.
