With this stitching chisel from Oka of Japan, you can ensure that your leathercrafts have consistently sized and spaced stitches. Unlike a diamond hole punch, this tool creates flat, slanted stitch holes on your leather to give it a unique finish. This tool has a non-slip handle for improved grip and control, allowing you to punch holes accurately and keep it from slipping during use. This tool is an excellent addition to your leathercraft tool collection as it has been tempered for increased hardness and sharpened by experts.

When sewing around the edges of your leathercrafts, use this 4 pronged diagonal hole punch. The size number is etched on the end of the handle, making it easier to select the appropriate size for your leather project.

  • Diagonal Hole Punch Ⅰ (3mm)
    • 1 prong

The sizes in mm are the spaces between prongs.

When punching holes or removing this tool from your leather, keep it perpendicular to your leather and use a soft-headed hammer instead of a metal hammer to avoid damaging the tool. The heavily tempered prongs of this tool have a dual purpose: not only are they extremely strong and ideal for penetration, but they also protect your leatherwork from uneven stitching by breaking, rather than bending, when overstressed. This prevents the tool from creating uneven stitch holes, which can occur with cheaper stitching chisels due to an undetected bent prong.

Please note: This tool has sharp prongs, keep out of reach of children. Store without the tool coming into contact with hard surfaces to avoid dulling the cutting edge.
