N690 Puukko Knife Blank - N83 (N83)

N690 Puukko Knife Blank - N83

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.

Every blank starts as certified Voestalpine stock. We profile and hand grind it in our own workshop, then send it back to Voestalpine for professional heat treatment.
