Aogami Blue Super Steel is another high end knife steel production by Hitachi.
Aogami is a carbon driven steel so whilst it will be very hard it will also be more likely to be corrosive - so for these knives you need to take care of them.
You will notice a much lower contribution of Chromium when compared with classics like VG10 or AUS10.
The steel composition is as follows:
