Robust knife with V-ground chisel function. The blade is made from Japanese knife steel, 3 mm carbon steel that has been hardened to 58-60 HRC. The cutting edge has been sharpened with a double edge angle and a final honing on a leather strop. Both the handle and holster are made from super-durable PP plastic. The holster can be attached to both a belt and a button on work clothes. If the belt is thick, the small pin on the cover can be cut away. The holster features a unique function for attaching it around a button on work clothes so that it does not come loose whilst still being easy to remove. Chisel knife STK-PH is supplied with a cardboard case instead of a holster. STK fits in the same holster as heavy duty knife GK.
