How to Use

How to Use

Mark your stitch line using a wing divider or creasing tool.
Position the stitching punch on the leather.
Strike firmly with a suitable mallet or maul on a punching surface.
Continue along the stitch line, using the last tooth to align each subsequent impression for perfectly even spacing.
Complete the project using traditional saddle stitching with two needles.

For best results, use on a firm and stable surface covered with a specialised mat, such as our leather punching mat. Hit the punch cleanly and firmly with a heavy leather mallet.

Why Choose Diamond Stitching Chisels?

Diamond stitching punches create angled holes that naturally guide the thread into the distinctive slanted stitch pattern prized in traditional leathercraft. Compared with round holes, diamond-shaped holes close more neatly around the thread, helping to create stronger, cleaner-looking hand stitching while preserving the appearance of the leather.
