The Hultafors Electricians Knife ELK from Hultafors.
The sharpening of the two blade edges and the design of the handle are optimised for cable stripping. The knife blade is made from Japanese 1.5 mm knife carbon steel that has been hardened to 58-60 HRC.
A unique method for attaching the sheath around a button on your work clothes means it does not loosen, but is easy to remove. The sheath fits just as well on your belt as on your buttons.
The handle and sheath are made from extra durable PP plastic.
