The invention relates to a tool having first and second cooperating jaws connected by a pivot. Each jaw includes a gripping surface and two side surfaces, and each jaw has a nose end that is remote from the pivot. Handle means causes the jaws to close about the pivot. There is a groove in the gripping surface of each of the jaws extending to the nose end of the jaw. The grooves lie along the longitudinal axis that lies in a plane extending between the gripping surfaces of the closed jaws. A cavity that is deeper than the grooves is formed in both of the jaws at the ends of the grooves opposite the nose.
