For smooth and efficient leather hand sewing use this handy, high quality leathercraft stitch punch, developed by Oka, a renowned Japanese manufacturer of premium leathercraft tools. This tool produces evenly spaced and sized diamond-shaped holes, ensuring you have professional-grade stitches for all your leather projects. Each prong is honed and the whole tool is tempered and covered in a rust-resistant coating, so you can have a tool that is long-lasting and will provide you with excellent service. For added comfort and control when punching holes, this tool also features a knurled non-slip handle.

This six-prong diamond hole punch can be used to punch multiple stitching holes quickly and easily in a straight line such as on the edges of your leather.

Size (space between tips of prongs):

  • 4mm

Available prong numbers (each sold separately):

  • 1-prong
  • 2-prongs
  • 3-prongs
  • 4-prongs
  • 6-prongs
  • 8-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 go undetected. 

Please note, the professional nature of this tool means it requires special care. 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 rock 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.
