Ensure your leather stitching is smooth and even with this high-quality diamond hole punch from Oka, a manufacturer of premium leathercraft tools based in Japan. Made from tempered steel with a rust-resistant coating, ensuring this tool will provide long-lasting, excellent service. This tool also features a knurled handle which makes the tool non-slip to keep it from slipping off your hand during use. Buy this tool along with other sizes and prong numbers to make your leather stitching easy and efficient.

This leather stitch punch produces six evenly sized and spaced diamond-shaped holes that is suitable for hand sewing leather. Use this tool to punch multiple holes at once on a straight line such as on the edges of your leather. 

Size (space between tips of prongs):

  • 5mm

Available prong numbers (each sold separately):

  • 1-prongs
  • 2-prongs
  • 3-prongs
  • 4-prongs
  • 6-prongs
  • 7-prongs

Please note, the prongs on this tool are highly tempered, which makes them very hard, but somewhat brittle, so that overstressed prongs would break off, rather than bend. This is by design, as bent prongs of lower quality pricking irons deform more easily, not only ruining the tool, but also have the potential to ruin your leatherwork by producing permanent uneven stitch holes if undetected. The highly tempered prongs of this quality tool have a dual purpose: To protect your leatherwork from uneven stitching by having the prong break, rather than bend, when overstressed. Safeguarding you from uneven stitching of a bent tool, while giving longer lasting points that require less sharpening and greater penetrating power. This dual feature is of great benefit as it gives you peace of mind, knowing there is no chance of even a single uneven hole to ruin the leather masterpiece you've spent many hours working on.

Always use a soft headed hammer (never metal) and tap it into your leather work gently, when removing, always pull it out of your leatherwork straight, never shift it side to side to loosen it or this could snap the prongs. Avoid using leather that is so thick it makes removal difficult. If you work with leather that is thick enough to make removal difficult then a wider pricking iron is recommended. Please store this tool away from other tools or hard objects, do not drop this tool or strike on a hard surface.

Keep out of the reach of children.
