Abstract: A rotatable wire wrap tool of the type having an apertured tip end operative to engage a terminal to wrap the terminal with wire as the tool is rotated, is provided with a bobbin carrying a supply of insulated conductor wire which is fed from the bobbin through the tool to its tip end. The interior of the tool is provided with a slitting element positioned to engage the surface of the wire as it is fed toward its wrapping position, to cut an elongated continuous slot through any insulation on the wire while leaving the remainder of the insulation intact, and the tool is further provided with an inclined face adjacent its tip end for guiding and twisting the slotted wire as the tool is rotated to bring the portion of the conductor wire which is exposed through the slot in the insulation into electrical contact with the terminal being wrapped.
