Cooperating jaws are pivoted together such that working end portions of the jaw members are movable toward and away from each other. The jaws have butt portions extending opposite the jaw pivot from the working end portions. Such butt portions are, in turn, pivoted to elongated handles for swinging about axes parallel to the axis of the jaw pivot. The handles are channel shaped and define recesses into which the interconnected jaw members can be swung so as to be nested in the handles or, alternatively, into which the interconnected jaw members can be retracted so as to be partially contained within the handles. The handles have forward portions interconnected by a tension spring, and cooperating cam surfaces to bias the handles to predetermined angular positions.
