Claim:
1. A pair of pliers for forming a hole in a non-flat material, said pliers comprising: a first member having a first handle on a proximal end of said first member and a first jaw on a distal end of said first member; a second member having a second handle on a proximal end of said second member and a second jaw on a distal end of said second member; wherein said first member and said second member are attached at least one connection point to permit pivoting movement between said first jaw and said second jaw such that said first jaw and said second jaw are opposed and adapted for moving with respect to each other in response to a force being applied to said first handle and said second handle; wherein said first jaw comprises a punch tip extending therefrom and configured to be received by an opening defining one end of a passage extending at least partially through said second jaw; and wherein said second jaw comprises a shaped edge being a straight line apex formed from two non-parallel, planar surfaces converging towards each other in a direction towards said first jaw; and wherein said shaped edge comprises said opening having substantially the same shape as a cross-section of said punch tip, and wherein said passage is configured to receive said punch tip therein upon the application of a squeezing force to said first and second handles.
