A powerful and durable ground knife suitable for coarse work such as prizing, breaking and hacking. The unique method for attaching the sheath around a button on work clothes means it does not loosen, but is easy to remove. The knife blade is made from 3 mm Japanese knife carbon steel, that has been hardened to 58-60 HRC with the cutting edge sharpened with a double edge angle and a final honing on a leather strop. The handle and sheath are made of extra durable PP plastic. This heavy-duty knife is more robust and therefore has a larger sheath compared to other craftsman's knives.
