N690 Puukko Knife Blank - N109
A puukko carries a straight edge and a hidden tang. That combination makes it light in the hand and easy to control for detail work in the field.
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.
