This is a simple keyhole punch. You can easily make a keyholder just by punching with this punch, sewing around the edges, and attaching a ring!!! Why not try making an original keyholder★ Ideally, you would use a press machine, but if you don't have one, you can also punch it out by tapping. Place the leather on top of the punch. Try tapping it with a rubber mallet or wooden mallet. Be careful not to touch the blade as it is sharp.
