A leather stitching punch is a metal tool with a group of round punches grouped in a straight line. When making holes along a leather’s edge that will be used for running leather lacing through, it is helpful to have the holes both be a consistent size, and a consistent distance between each other.
If this is done with a standard hole punch, each hole needs to be measured, lined up, and punched. A stitching punch makes this much easier as hitting it once will punch several holes into the leather at the same time. Stitching punches might have 3, 5, or more blades.
The size of the holes and the number of blades available varies, so the crafter can choose one or more stitching punches that would help most for their particular project.
