A punch for punching a sheet of material is provided. The punch has a body with a fissure, a pivot shaft defining a pivot point and a lever retainer secured to said body. The lever is pivotably mounted about the pivot point and has an open position and a closed position. A block is positionable between the lever and the body. The body has longitudinal support ridges and side ridges with the pivot point being 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.

1. A punch for punching a sheet of material, said punch comprising: a body formed with a fissure for receiving the sheet of material;a lever having a front portion pivotably mounted to said body and a rear portion opposite said front portion, said lever also including a central longitudinal ridge pair disposed on an underside of the lever and a raised bump positioned between the central longitudinal ridge pair, the central longitudinal ridge pair closer together towards the front portion of the lever and further separated from one another towards the rear portion of the lever;a block positionable between said lever and said body, said block having a shaped punch movable along a first axis, said block further comprising first, second, and third shoulders; andfirst, second, and third resilient members, said resilient members disposed adjacent to said die and disposed between said first, second, and third shoulders of said block and said body;wherein when said block is positioned between said lever and said body, and when said lever is pivoted between a first open position and a second punched position, the bump between the central longitudinal ridge pair on said lever engages said block having said axially moveable shaped punch to punch said sheet of material. 2. The punch of claim 1, wherein said first and second shoulders are positioned approximately 30 degrees about said block from a second axis along the horizontal length of said punch, and wherein said third shoulder is positioned approximately within said second axis. 3. The punch of claim 1, wherein when said lever is pivoted to said second punched position, said lever is substantially parallel to said fissure. 4. The punch of claim 1, further comprising a locking assembly operable to secure said lever in said second punched position, such that said lever is locked in a closed position parallel to said fissure. 5. The punch of claim 1, wherein said body further comprises a front nose portion, said front nose portion having a flattened surface so that when said punch is locked in said closed position and positioned upright in a stored position on said flattened surface, said punch rests in a substantially vertical orientation. 6. The punch of claim 1, wherein said body includes longitudinal support edges and said lever includes side ridges, wherein when said punch is closed, said side ridges of said lever pass outside of said support edges of said body in a nesting relationship, allowing said punch to form a flat profile when closed. 7. The punch of claim 1, wherein said block has a flat upper surface above said die, and wherein said shoulders are raised relative to said flat upper surface. 8. The punch of claim 7, wherein said first and second shoulders are positioned substantially 60 degrees apart from one another and each substantially 150 degrees apart from said third shoulder. 9. The punch of claim 7, wherein said longitudinal ridge pair is configured to be separate around said third shoulder, and tapers together towards said front portion to pass between said first and second shoulders. 10. The punch of claim 7, wherein said longitudinal ridge pair is configured to be separate around said third shoulder, and tapers together towards said front portion to pass between said first and second shoulders, allowing said lever to engage said block in a manner that allows said punch to form a flat profile when closed. 11. A punch for punching a sheet of material, said punch comprising: a body formed with a fissure for receiving the sheet of material;a lever pivotably mounted to said body for pivotal movement about a pivot point, said lever having an open position in which one end of said lever is elevated to a height above said pivot point, and said lever having a closed position in which said lever is positioned parallel to said fissure, said lever also including a central longitudinal ridge pair disposed on an underside of the lever and a raised bump positioned between the central longitudinal ridge pair, the longitudinal ridge pair closer together towards a front portion of the lever and further separated from one another towards a rear portion of the lever;a locking mechanism operable to secure said lever in the closed position;a block positionable between said lever and said body, said block having a shaped punch movable along a first axis, said block further comprising a seat configured to receive said lever; andat least one resilient member adjacent to said die, and disposed between said block and said body, wherein when said block is positioned between said lever and said body and when said lever is pivoted about said pivot point between a first and a second point, the bump between said longitudinal rib pair engages said block having said axially movable shaped punch to punch said sheet of material,wherein said body further comprises longitudinal support edges and said lever further comprises side ridges, and wherein when said punch is closed, said side ridges of said lever pass outside of said support edges of said body in a nesting relationship, allowing said punch to form a flat profile when closed. 12. The punch of claim 11, wherein the longitudinal support edges are located in substantially the same horizontal plane as said pivot point. 13. The punch of claim 12, wherein said block has a flat upper surface above said die, and comprises first, second, and third shoulders, wherein said shoulders are raised relative to said flat upper surface. 14. The punch of claim 13, wherein said first and second shoulders are positioned substantially 60 degrees apart from one another and each substantially 150 degrees apart from said third shoulder. 15. The punch of claim 14, wherein said longitudinal ridge pair contacts said upper surface of said die, wherein said longitudinal ridge pair is configured to be separate around said third shoulder, and tapers together towards said front portion to pass between said first and second shoulders.
