The Gro (meaning "grow") belt knife from the Norwegian manufacturer Helle is the big brother of the Spire knife. The very sharp blade is made of 12C27 Sandvik stainless steel and is a real all-rounder for camping use. Dark-coloured birch wood gives the ergonomically designed handle with finger guard its special look. The perfectly fitting leather sheath with belt loop made from natural leather is adorned with stylised tree rings to remind the owner that learning is a constant process of growth.
