When stitching leather, use this Oka stitching chisel to make stitch holes that are uniform in size and spacing. Instead of a diamond-shaped hole, this tool punches slanted, flat slits in your leather for clean, professional-looking stitching. Each prong is polished, and the entire tool is tempered, resulting in a tool that will endure a long time and give excellent service. This tool has a non-slip handle for a better grip and to prevent the tool from slipping while punching holes.

This high-quality six-prong stitching chisel is ideal for making diagonal holes over long distances, such as in your leather's edges.

The sizes in mm are the spaces between 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 larger stitching chisel is recommended. Please store this tool away from other tools or hard objects, do not drop this tool or strike on a hard surface.

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.
