Think of this Yasutomo paper punch as the Yankee screwdriver’s younger, more specialized cousin. Pressure on the handle turns the center shaft so that the hollow, sharpened tip cuts easily into paper, fabric, or leather. It’s designed for bookbinding, but it’s great for leatherwork, too.
Nasco, the online arts and crafts distributer where I found this tool, says it’s also good for polymer clay work. They also sell replacement tips in three different sizes, so you don’t have to sweat sharpening a difficult shape.
