N690 Puukko Knife Blank - N87
The puukko is Finland's contribution to knife design and still one of the most practical patterns ever drawn. Short, stiff, and shaped for carving.
Böhler N690 is the stainless most outdoor makers settle on. Cobalt and vanadium give it fine grain and real edge retention, and 17% chromium means it survives a wet pack.
Steel sourced from Voestalpine, hand ground by our team, then heat treated professionally at the mill. Every blank arrives at working hardness.
