AUS-10 Stainless Steel for Knife Blades

AUS-10 Stainless Steel

Manufacturer: Aichi Steel

AUS-10 is the top of the line steel from AUS series of steels from Aichi Steel in Japan. AUS-10 is in a similar class of steel as 440C, but possibly out performs 440C due to the additional carbon and vanadium.

Not a lot of production knives use AUS-10, and tend to lean towards 440C or 154CM when using steels in that class. In fact, the only knife I've ever seen in this steel is one run of the Spyderco Native, and have never actually used it myself.
