ABSTRACT OF THE DISCLOSURE A wire stripper tool having a pair of arms connected at a pivot intermediate the ends thereof, one arm having an anvil at one end and the other arm having an opposed cutting head which supports a blade at the front of the head for slitting the wire insulation longitudinally, and a blade at each side of the head for slitting the insulation circumferentially. The anvil has a seat extending normal to the second- named blades for positioning the wire while being slit. A spring is located between the pivot and the cutting blades and normally biasing the cutting head to a closed position relative to the anvil. The arms have opposed inner surfaces which are divergent rearward of the pivot to enable the arms to be squeezed together rearward of the pivot thereby to move the cutting head to an open position relative to the anvil which allows a wire to be positioned in the seat for slitting. The inner surface of one arm is slotted and the inner surface of the arm opposed thereto has a guide rib with one end disposed in the slot in both the open and closed position of the cutting head. With the construction of the disclosed wire stripper, there is reduced the likelihood of incomplete or irregular slits due to the spring coil being used as a pivot, due to the inability to achieve acceptable parallelism with a pair of guide flanges and due to the form of the spring in the known tool.
