Abstract

A safe means for a cutting mechanism attachable to a remote power source and enclosed within a rigid semi-curved sheath. The sheathed cutting means of the invention is provided with a flexible power transmission means for connection to a remote power source. The flexible power transmission means is comprised of a two-ended blade, one end of which is connected to the power source and the other end of which is capable of acquiring a sharp edge. By means of the rigid slightly curved protective sheath, the blade can be introduced past the dash moldings and garnishings in a vehicle from the inside of the vehicle next to the interior window or windshield so that the cutting blade alone is brought into contact with the polyurethane seal and the seal is quickly and safely severed without breaking the windshield.
