N690 Tanto Style Japanese Chef Knife Blank - NC08 (NC08)

N690 Tanto Style Japanese Chef Knife Blank - NC08

The tanto profile is unmistakable. Its hard-angled tip gives precision for scoring and trimming, and the flat main edge handles ordinary chopping without fuss. The blade measures 230 mm, 325 mm overall.

N690 hits the balance most makers want: it takes a keen edge, holds it through a service, and sharpens back without a fight. The high chromium content makes it forgiving around acidic food and standing water.

Our process is deliberately simple: certified Voestalpine steel, hand grinding in our workshop, then professional heat treatment back at Voestalpine. That is why the hardness figures below are reliable.
