The plier of the invention generally comprises a handle assembly, a C-shaped clamping section, and an extension arm disposed above one of the jaws of the C-shaped clamping section and adjustably extending longitudinally to an outer-point. A pressure post is provided at an outer end of the extension arm and a counter pressure post is provided within the jaws of the C-shaped clamping section to provide opposed counteracting forces along the longitude of one or more objects grasped by the plier to secure the object(s) stably within the grasp of the plier.
