POWER SKINNING KNIFE WITH UNIDIRECTIONAL ROTATING BLADE

摘要

A power skinning knife having a disc shaped blade (12) driven in unidirectional rotary motion with a pair of blade shields (18) on opposite sides of the blade covering most of the blade and exposing only a limited depth arcuate cutting region of the blade between the perimeter of the shield and the cutting edge. The blade is driven by a motor geared to turn first and second toothed pulleys (48, 52) connected by a toothed belt (50). The blade may be circular or lobed and mounted concentrically or offset to provide either a smooth or pulsing cutting action. The tool may also include a wiping element (70) which removes debris from the blade edge before it enters the tool housing and a steeling element (68) which can be actuated by the operator's thumb while the tool is being used to sharpen the blade.
