Extremely rare historical steel produced by Andrews Steel Company in the late 19th century. Known for achieving White #1 levels of keenness with Blue Super edge retention. Notoriously difficult to forge, requiring master-level heat control. Tools made from this steel are among the most coveted in the world.

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.
