A power skinning knife having a single substantially disc shaped blade driven in continuous unidirectional rotary motion with a pair of blade shields 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 pneumatic motor that is geared to turn first and second toothed pulleys connected by a toothed belt. 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 which removes debris from the blade edge before it enters the tool housing and a steeling element which can be actuated by the operator's thumb while the tool is being used to sharpen the blade. |
