The Nagahiro workshop in Sanjo is one of the premier producers of Aogami Super plane blades — a steel demanding rare skill to forge and heat-treat correctly. They are particularly noted for their control of carbon migration at the lamination weld line between the high-carbon cutting steel and the soft iron body, producing a blade that is both extremely hard at the edge and shock-resistant at the spine.
