N690 Puukko Knife Blank - N52 (N52)

N690 Puukko Knife Blank - N52

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.

Certified Voestalpine steel, hand ground in our workshop, professionally heat treated by Voestalpine before it ships. That is the whole process.
