Oka, a well-known Japanese manufacturer of quality leathercraft tools, created this handy leathercraft stitch punch for smooth and efficient leather hand stitching. For all of your leather projects, this tool can be used to make diamond-shaped holes that are precisely spaced and sized, ensuring professional-grade leather stitching. Each prong is sharpened and tempered, with the body of the tool coated with a rust-resistant coating to ensure that you get a tool that will last a long time and give outstanding service. This tool also has a non-slip grip for improved comfort and control when punching holes.

Quickly and easily punch multiple stitching holes in a straight line, such as on the leather's edges, with this six-prong diamond hole punch.

Size (space between tips of prongs):

  • 3mm

Available prong numbers (each sold separately):

  • 1-prongs
  • 2-prongs
  • 3-prongs
  • 4-prongs
  • 6-prongs
  • 10-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 the bent prongs remain 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.
