ABSTRACT:
In a motor-driven cutter for the cutting open of plaster casts with a motor housing, a fixed center blade and two oscillatingly motor-driven blades disposed either side of the fixed blade and both interacting with said fixed blade and moving the cutter forward along the cut, in order to prevent unitentional contacting of the blades, it is proposed that a cover hood be displaceably mounted on the motor housing and be displaced by a flexible force storage means into a position covering the three blades whereby the cover hood exhibits glide-on surfaces which, as the cutter is pushed forward, glide on the plaster, thereby displacing the cover hood against the action of the flexible force storage means into a position exposing the blades.
