Electrician's Knife ELK The sharpening of the blade edges and the design of the handle have been optimised for cable stripping. It features a unique function for attaching the holster around a button on your work clothes so that it does not come loose whilst still being easy to remove. The blade is made from Japanese knife steel, 1.5 mm carbon steel that has been hardened to 58-60 HRC. The two edges have been sharpened to be particularly effective when stripping cables. 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 your work clothes. If your belt is thick, cut away the small pin on the cover. ELK-L has a green handle with edges sharpened for left-handed use.
