Abstract
A cutting edge of a punch includes side segments and a central segment disposed between the side segments. When the punch head slides into a hollow blade, the central segment of the cutting edge meets the punch head before the side segments meet the punch head. The central segment starts cutting first, which can help avoid a dog-bone shaped hole when the punch is used on a blood vessel, such as the aorta.
