ABSTRACT:
The invention includes pliers with self-adjustment capability for applying an initial grasping force to a workpiece and for augmenting the initial grasping force applied to the workpiece. The pliers are structured such that angular displacement of a handle portion of a first plier member is smaller than angular displacement of a jaw portion of the first plier member during an initial movement of the handle portions toward each other for applying the initial grasping force to the workpiece. In addition, the pliers are structured such that angular displacement of the handle portion of the first plier member is larger than angular displacement of the jaw portion of the first plier member to permit augmenting of the initial grasping force applied to the workpiece during a continued movement of the handle portions toward each other.
