N690 Knife Blank - N70 (N70)

N690 Knife Blank - N70

A hardened, ground blade blank ready for handle work. The heat treatment is done and the geometry is set — everything after this is yours. A full tang knife blank, so the scales pin straight to the steel.

N690 balances edge life against corrosion resistance better than almost anything in its price band. It sharpens back easily and shrugs off moisture.

Steel sourced from Voestalpine, hand ground by our team, then heat treated professionally at the mill. Every blank arrives at working hardness.
