A pair of pliers for gripping, twisting, and cutting wires having undulating wire gripping surfaces, a wire cutting cavity, and a resilient wire gripping material. The undulating wire gripping surfaces have high and low portions that unequally traverse the gripping surfaces and extend unequally beyond the centerline of the pliers. Such a configuration provides an equally distributed gripping force for an entire range of wires without causing any nicks and scrapes on the wire. The cutting cavity has a plurality of surfaces that form tiger tooth-like members. The geometry formed by the cavity's surfaces and tooth-like members provides a large surface area for the resilient gripping material to adhere to.

Plier-type tool for gripping, twisting, and pulling wires

A reversible wire twisting plier tool is provided, which includes a pair of plier arms each having a jaw portion and a handle portion and which are pivotally interconnected and movable between an open position and a closed position. A plier rotating mechanism is mounted on one of the handles. The rotating mechanism includes a tubular member and a double spiral shank having a left hand groove and a right hand groove, axially slidably mounted within the tubular member. First and second gears are disposed within the tubular member, one gear being slidably engaged in one of said grooves and the other being slidably engaged in the other groove. A gear actuator is provided which is movable between a first actuated position wherein the actuator engages the first gear and a second actuated position wherein the actuator engages the second gear to selectively impart a clockwise or counterclockwise motion to the shaft depending upon which gear means is engaged. A reversing mechanism is mounted on the tubular member and connected to the gear actuator. The reversing mechanism includes a sleeve which is rotatably movable between first and second positions corresponding to the first and second actuated positions of the gear actuator. A mechanism is also provided to releasably latch the pliers in the closed position and automatically release the pliers from the closed position upon squeezing thereof.
