- and
- d) second means for releasing said movable portion from said fixed portion in order to release the workpiece using only the one hand;
- e) pivotable lever;
- f) a first lever pivot pin;
- and
- g) a second lever pivot pin;
- wherein said movable portion is movably connected to said fixed portion;
- wherein said first means is operatively connected to said fixed portion;
- wherein said second means is operatively connected to said movable portion;
- wherein said fixed portion comprises:
- a) a fixed upper jaw;
- and
- b) a fixed upper handle;
- wherein said fixed upper handle of said fixed portion extends fixedly from said fixed upper jaw of said fixed portion;
- wherein said movable portion comprises:
