OKA Factory Diamond Stitching Chisels

This diamond stitching chisel is made by OKA Factory in Japan with exceptional precision and quality, perfect for leathercraft.

This diamond stitching chisel is fully tempered for exceptional durability, ensuring it won’t bend or deform during use.

Each blade is individually sharpened and polished to prevent any damage to the leather when removing the tool after punching. The blade edges are shaped like those of a traditional Japanese katana, with an extremely sharp angle that creates narrow, clean holes.

The handle features a non-slip textured pattern for a secure grip. A black coating helps prevent rust, and each chisel has its size engraved for easy identification. The blade is also covered with resin for protection.

Sizes indicate the spacing between prongs.

Note: Do not use a metal hammer, as it may cause deformation and damage the plating, leading to rust. Instead, use a wooden hammer, maul, or mallet.
