A de-hiding tool includes a handle section with a long blade cover, a pair of counter-rotating and oscillating cutting disks mounted face-to- face and driven by eccentrically mounted drive arms operated by a self- contained air motor, a short blade cover mounted to a side of the cutting disks opposite from the long blade cover, and an adjustable blade support which includes an adjustment shaft extending through the blade covers and providing a means for adjusting the spacing between the blade covers from the outside of the tool housing. The blade adjustment system includes an insert with threads accessible from the outside of the housing to adjust the size of a gap between the blades by corresponding movement of a spacer inside the cover. This controls the face-to-face pressure on the blades to make them cut more efficiently and to compensate for the blades being ground thinner when resharpening the blades.
