Abstract
In a hand tool, a pair of elongated tool arms interconnected by a pivot, a torsion spring having legs which are connected respectively to the tool arms to bias the arms to an open position, and a plier lock element member having a spaced pair of eyes and a connecting bridge, with the plier element being slidably connected to the torsion spring legs such that the element is movable between locking and release positions. When in the lock position, the element is near the spring interconnection and acts to restrain the spring from biasing, and to inhibit relative work movement of the tool arms. When in the release position, the element selectively permits work performing movement of the arms about the pivot. One of the spring legs includes a working offset portion, and each of the spring legs includes a locking offset portion located near its connection with the associated one of the tool arms.
