4. The clamping system of claim 2 , wherein at least one of the cam ( 76 ) and the locking bar ( 74 ) includes an abrasive surface.

5. The clamping system of claim 1 , wherein the first jaw ( 40 ) comprises a pad ( 24 ) pivotally connected at the second end of the first jaw ( 40 ).

6. The clamping system of claim 1 , wherein the second jaw ( 50 ) comprises a pad ( 26 ) pivotally connected at the second end of the second jaw ( 50 ).

7. The clamping system of claim 1 , wherein the second lever arm ( 130 ) comprises a first and a second portion, each portion extending away from the second pivot ( 126 ), wherein the first and second portions define an angle therebetween that is less than 180 degrees.

8. The clamping system of claim 1 , wherein the first lever arm ( 114 ) between second pivot ( 126 ) and third pivot ( 112 ) defines a first longitudinal axis ( 118 ), wherein the first potion of the second lever arm ( 130 ) between the second pivot ( 126 ) and the fourth pivot ( 134 ) defines a second longitudinal axis ( 138 ), wherein the first axis ( 118 ) of the first lever arm and second longitudinal axe ( 138 ) of the second lever arm define a first angle when the clamping system is in the first closed position and define a second angle when the clamping system is in the second open position, and wherein the first angle is less than the second angle.

9. The clamping system of claim 8 , wherein the first angle is between about 10 degrees and about 40 degrees.

10. The clamping system of claim 8 , wherein the first angle is between about 20 degrees and about 30 degrees.

11. The clamping system of claim 9 , wherein the third pivot ( 126 ) is positioned below the first longitudinal axis ( 118 ) when the clamping system is in the first closed position, and the third pivot ( 126 ) is positioned above the first longitudinal axis ( 118 ) when the clamping system is in the second open position.

12. The clamping system of claim 1 , wherein the adjustment element ( 72 ) comprises a rotatable threaded element.

13. The clamping system of claim 1 , wherein the adjustment element ( 72 ) comprises a serrated element and an interlocking pin element.

14. The clamping system of claim 1 , wherein at least one of the first and second jaws ( 40 , 50 ) defines a curve.

15. The clamping system of claim 1 , wherein the first and second jaws ( 40 , 50 ) define respective curves with the arc of each curve extending in opposite directions.

16. The clamping system of claim 1 , wherein the locking handle ( 60 ) defines a curve.

17. The clamping system of claim 1 , wherein the first jaw ( 40 ) and the locking handle ( 60 ) each define curves whose respective arcs extend in the same direction.

18. A clamping system comprising:

a first jaw ( 40 ) having first and second ends;

a second jaw ( 50 ) having first and second ends, the second jaw ( 50 ) being pivotally connected to the first jaw ( 40 ) at a first pivot ( 100 ) located at the respective first ends of the first and second jaw ( 40 , 50 );

a locking handle ( 60 ) having first and second ends the first end of the locking handle connected to the first pivot ( 100 );

a first lever arm ( 114 ) having a first end and a second end; and

a second lever arm ( 130 ) having a first end and a second end, the first end being pivotally connected to an adjustment element ( 72 ) at a second pivot ( 142 );

wherein the first end of the first lever arm ( 114 ) is pivotally connected to the second lever arm ( 130 ) at a third pivot ( 126 ) positioned between the first and second ends of the second lever arm ( 130 ), and the second end of the first lever arm ( 114 ) is pivotally connected to the first jaw ( 40 ) at a fourth pivot ( 112 ),
