This Oka premium stitching chisel is ideal for punching holes suitable for sewing leather. This French-style hole punch creates flat, diagonal prongs rather than diamond shaped, which is ideal for giving your leather a distinct, smooth finish. This tool is honed and polished by professional craftsmen to guarantee that it is easily removed without damaging your leather.

This two-prong French-style stitching chisel is great for adding holes around curves or for adding flat stitch holes on smaller leather projects.

The sizes in mm are the spaces between prongs.

Because the prongs of this tool are highly tempered, making them hard yet brittle, they will break off rather than bend when overworked. This is due to the design, which prevents it from causing uneven thread holes in your leatherwork. The tempered prongs have two benefits. First, rather than bending, they snap off to safeguard your leatherwork from uneven stitching, which is not the case with cheaper pricking irons that bend and ruin your leatherwork with uneven stitch holes. Second, it offers long-lasting prongs that not only require less honing but also have more penetrating force. These qualities provide the user with peace of mind, knowing that it will not harm the leathercrafts they have worked so hard to create.

If you use this tool, be sure you use a soft-headed hammer. To prevent breaking the prongs, never pull it side to side when attempting to pull it from your leather; instead, draw it perpendicular to the leather with the tool. A larger size may be suitable if you find it difficult to remove from your leather. Keep this tool at a safe distance from other tools and materials. Finally, try not to drop it or strike it against a hard surface.
