Abstract
A tool such as a vise or a pair of pliers has two relatively movable jaws linked via respective shanks with operating means such as a pair of handles, each jaw comprising an elongate base with upstanding parallel webs having workpiece-engaging faces alternately inclined in opposite directions. To facilitate the interfitting of these webs in a working position, particularly with pivotally interconnected shanks whose pivotal axis parallels the planes of the webs, the jaws are swingably mounted on their shanks with swing axes parallel to the pivotal axis. One shank is connected to its handle by way of an interposed resilient pad of adjustable elasticity.
