N690 All Purpose Kitchen Blade M size
A medium all-purpose profile is the safe first build. Familiar proportions, no awkward geometry, and a shape that gets used daily.
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.
