A hand-held, electrically-powered device designed for cutting the plaster or synthetic material used to form casts typically during the removal process. The proximal end is usually cylindrical, forming the handle of the device, whilst the distal end terminates in a rounded, half moon-like, or circular blade capable of cutting the material used to form casts. The cutting capability of the blade is provided by an electric motor in the handle which vibrates or rotates the blade. Cutting is effected by vibration or rotation rather than sawing.
