A hand tool of the toggle link or vice grip type provided with structure operative to oppose opening movement of the handles when the latter are oriented relative to the toggle linkage in locking condition in the absence of any reactive force from a workpiece. Such structure takes two basic forms, namely, (a) the compression member of the toggle linkage being swivelly connected at its opposite ends to the handles to hold its swivel connections spaced a substantially constant amount at all times, with coacting detent means carried by one of the handles and the compression member for yieldingly resisting relative movement of such elements from their locking positions, and (b) the provision of structure for limiting closing movement of the members that carry the work engaging elements, whereby such limiting action will result in reactive forces equivalent to the work engaging elements being loaded against a workpiece by closing movement of the handles. Such structure for limiting closing movement of the members can be such as to be subjected to compressive, shear or tensile stresses in the performance of its movement limiting function.
