Punchcutting is a craft used in traditional typography to cut letter punches in steel as the first stage of making metal type.[1] Steel punches in the shape of the letter would be used to stamp matrices into copper, which were locked into a mould shape to cast type. Cutting punches and casting type was the first step of traditional typesetting.[2] The cutting of letter punches was a highly skilled craft requiring much patience and practice. Often the designer of the type would not be personally involved in the cutting.

The initial design for type would be two-dimensional, but a punch has depth, and the three-dimensional shape of the punch, as well as factors such as the angle and depth to which it was driven into the matrix, would affect the appearance of the type on the page. The angle of the side of the punch was particularly significant.
