Tamahagane vs Aogami Super

The legendary steel produced by smelting iron sand (satetsu) in a traditional tatara furnace over three days. The bloom contains steel at varying carbon levels, which a swordsmiths then separates by eye. For tool use, the finest pieces are laminated into a hard hagane cutting edge. Represents the absolute summit of Japanese metallurgical tradition — both material and art object.

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.
