One or more sheets of paper are inserted between the head and the die, with the flat face of the head parallel to the surface of the sheets. Moving the handle pushes the head straight through the sheets of paper. The hard edge of the punch vs the die cuts a hole in the paper, pushing the cut piece out the bottom of the die.
Die and punch shapes affect the force during the punching process. The punch force increases during the process as the entire thickness of the material is sheared at once.

Punched pockets have several holes in the left edge, which allow them to be bound into a file folder or ring binder. The holes in the punched pockets dispose of the difficulty of making holes in a paper document.
