The Hultafors Craftsman's Knife HVK BIO is a more sustainable option to our popular craftman’s knife. Made from a bio-based plastic, its unique design uses less material, reducing the environmental impact. There is also a hole for a strap, enables you to secure the knife when working at heights. Its blade is made from 2.5mm carbon steel and has been hardened to 58-60 HRC. The cutting edge has been sharpened in several stages, with a final honing on a leather strop.
