Abstract
A punch tool for the punching of a shape through a sheet of material. The punch tool includes a punch and a die portion disposed within a housing having a slot for receiving a sheet of material. A lower ramp is disposed within the housing and, when rotated, raises the punch to engage the die. The lower ramp may be rotated regardless of the orientation of the punch tool. Thus, the punch tool may be used even when in an inverted position.
