DIY Leather Tool Stainless Steel 2510 Prong Flat Leather Chisel Craft Tools Prong Hole Piercing Hole Punch Tool Kit 3.38mm

These pricking irons come in a set and are designed to make holes in leather for stitching. The Q&A section clarifies the measurements and distances of the irons. Customer reviews are mixed, with some praising their sharpness and ease of use, while others found them to be poor quality and easily breakable. The sides of the individual teeth are not polished, which can cause the irons to stick in the leather and leave imperfections in the stitch lines. Overall, these pricking irons are affordable and work well for basic leather stitching projects, but may not be suitable for high-end leatherwork.
