N690 Knife Blank - N31 (N31)

N690 Knife Blank - N31

A hardened, ground blade blank ready for handle work. The heat treatment is done and the geometry is set — everything after this is yours.

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.

We buy steel direct from Voestalpine, grind each blade by hand on the belt grinder, and return the blanks to Voestalpine for heat treatment done to spec.
