Produce diamond stitch holes on narrow, rounded corners of your leather with this two-prong leather stitch punch. This diamond hole punch is made of high-quality materials and has a rust-resistant finish, making it a great addition to your leathercraft tool collection. To easily identify the correct size for your work, the size number is etched in the end of the handle.

  • 4mm

Available prong numbers (each sold separately):

  • 1-prong
  • 2-prongs
  • 3-prongs
  • 4-prongs
  • 6-prongs
  • 8-prongs

When overstressed, the prongs of this tool will break off rather than bend because they are heavily tempered, making them hard yet somewhat brittle. This is due to its design, which prevents the stitch holes in your leatherwork from being uneven. Tempered prongs provide two advantages: Firstly, the prongs snap off rather than bend, protecting your leatherwork from uneven stitching, which is not the case with cheaper pricking irons, where an undetected bent prong can ruin your leatherwork with uneven stitch holes. Second, it provides long-lasting tips that require less honing and have more penetrating power. These characteristics provide the user peace of mind, knowing that the leathercrafts they have worked so hard to make will not be damaged.

Make sure you use a soft-headed hammer if you use this pricking iron. When attempting to remove it from your leather, never rock it side to side; instead, pull it perpendicular to the leather to avoid breaking the prongs. Keep this tool at a safe distance from other tools and materials.  Avoid dropping it or striking it against a hard surface.

Keep out of the reach of children.
