Leather corner punches are metal tools with sharp, rounded edges used to cut through leather. Corners on leather projects can be cut by hand, which requires measuring, then carefully cutting out the curved shape. Alternatively, using a corner punch makes this much easier. The corner shape is set as a metal blade and can simply be placed onto the material and hit with a mallet, hammer, or maul to make the cut.
Corner punches are available in different sizes so one can be found that matches the crafter’s need. If there are preferences for more rounded, or more angled corners, different diameters are available as well. If you’re cutting many similarly-sized piece with rounded corners by hand, these punches can definitely a valuable addition to your tool set.
