Aogami #2 vs Aogami Super

Detailed metallurgical comparison between Blue Paper Steel #2 and Super Blue Steel.

AOGAMI-2

Aogami #2

Blue Paper Steel #2

Similar to Aogami #1 but with slightly lower carbon and tungsten content. Offers an excellent balance of edge retention and toughness, making it the most-used steel among Japanese master blacksmiths. The sweet spot of the Aogami family — demanding enough to be worthy, forgiving enough to be reliable.

AOGAMI-SUPER

Aogami Super

Super Blue Steel

The highest-carbon variant among Aogami steels. Includes vanadium and molybdenum for extreme edge retention and hardness. Revered and feared in equal measure — its edge outlasts almost everything, but requires a master's touch to sharpen properly. The pinnacle of the Hitachi carbon steel family.
