Abstract: The hand held tool for cutting the sheath of a cable or insulated conductor is comprised of a durable plastic body, aluminum components which make up the blade adjustment mechanism and stainless steel hardware. The spring loaded blade adjustment mechanism allows the user to cut into the cable sheath or conductor insulation at various depths. The roller bearing guide in conjunction with the stepped thumb grip allows the user to easily insert the cable as well as perform the process of cutting the cable sheath or insulated conductor. Standard utility knife blades are used as the integral component for cutting the cable sheath or conductor insulation. A compartment for storing extra utility knife blades is located in the body of the tool.
