What steel grades are used in Zangetsu sword replicas?
Updated Feb 2026
The Zangetsu replicas in this collection are produced in 1045, 1060, and 1065 carbon steel — each chosen for specific performance characteristics. 1045 carbon steel offers reliable hardness and a clean surface that holds black coatings well, making it ideal for the dark Bankai aesthetic. 1060 is slightly harder and produces a finer grain on polished surfaces, which matters when the blade is displayed under direct lighting. The 1065 manganese steel used in the Nozarashi replica adds enhanced toughness and resistance to surface stress, which is particularly appropriate for a blade design as rugged as Kenpachi's. Understanding these distinctions helps collectors choose a replica that meets both their visual preferences and long-term display expectations.
