Blue (Aogami) #2 (Hitachi Metals Ltd.) is made by adding Chromium and Tungsten / Wolfram to White Steel #1. This results in increased toughness and the production of hard carbide molecules, which improve edge retention. Many knife users have noted that while Blue Steel #2 is very similar to White Steel #1 in terms of edge sharpness, it has slightly superior edge retention.
