How to Use
How to Use
How to Use Diamond Stitching Chisels
Begin by marking your stitch line using a wing divider, creaser, or stitching groover. Position the chisel on the line and strike it firmly with a leatherworking mallet to create evenly spaced holes through the leather.
For long straight sections, use the 8-prong chisel to maximise efficiency. Switch to the 5-prong or 2-prong chisel when working around curves, corners, or detailed areas. To maintain perfect spacing, align the first tooth of the chisel with the final hole from the previous strike before continuing along the stitch line.
Once the holes have been created, saddle stitch using your preferred needles and thread to achieve a strong, professional finish.

Why Choose Diamond Stitching Chisels?
Diamond stitching chisels are among the most popular tools in modern leathercraft due to their ease of use and reliable results. The diamond-shaped teeth create angled holes that allow stitching thread to sit naturally within the leather, producing the attractive slanted stitch appearance associated with quality handmade leather goods.
Unlike marking-only pricking irons, stitching chisels are designed to punch fully through the leather, allowing stitching to begin immediately without additional hole preparation.
