This Tsunehisa knife has a cutting core of aogami super. The blade side is black with a vivid tsuchime pattern.
Aogami super is NOT stainless, although its much less reactive than other carbon steels. The outer layers of the core are stainless which makes it even easier to keep rust away. You still need to to wipe off all moist directly after use to avoid rust.
Disclaimer: Japanese knives have thin edges with high hardness. This makes them much more fragile than traditional european knives. These blades should under no circumstances be subject to twisting, prising or cutting into hard objects. Such handling could easily cause damage to the edge, something that is not valid ground for a warranty claim.
