Tsunehisa AUS-8 Tsuchime Kiritsuke Knife, Pakka Wood handle,

The blade consists of 2 layers of steel - the harder steel AUS-8 (60 HRC) and a layer of softer stainless steel are forge welded together in what is known as "nimai" construction. AUS-8 steel is a popular Japanese steel from the Aichi steelworks that is incredibly resistant to rust, yet simple to sharpen. The steel contains high amounts of carbon (0.7-0.75%) and is also high in vanadium (0.10-0.26%) and molybdenum (0.10-0.30%). It also has a high percentage of chromium (14.5%), making the blade corrosion-resistant and increasing the hardness, durability and the tensile strength of steel mix. 

This carefully balanced composition does not only endow the blade with exceptional hardness (60 HRC) but also good wear and tear and rust-resistance properties.
