Abstract: A cast cutter having a pair of juxtaposed, sawedged blades which oscillate relative to each other on a common pivot point to provide a scissorslike cutting action resulting in a relatively wide kerf in the cast being out. A patient protective blade guard, slidable between the underside of the cast and the patient's skin, includes an aperture into which portions of the blades partially extend wherein a nip area is provided at an interface location of the blades and the guard to facilitate cutting of an inner woven cloth lining of the cast to the scissor teeth. The oscillatory motion of the blades relative to each other minimizes clogging thereof by dust particles generated during a cutting operation. The blades are slightly spaced from each other to preclude friction generated heat buildup that could result from the moving blades rubbing together.
