A punch for punching a sheet of material, the punch having a body formed with a fissure for receiving the sheet of material, a pivot shaft defining a pivot point, and a lever pivotably mounted about said pivot shaft has an open position and a closed position. A block is provided which is positionable between the lever and the body. The body is provided with longitudinal support ridges and the lever is provided with side ridges, with the pivot point positioned in substantially the same plane as the longitudinal support ridge so that when the punch is closed, the side ridges of the lever pass outside of the support ridges of the body in a nesting relationship, allowing the punch to form a flat profile when closed.
