What steel is used in these Nidai Kitetsu replicas?
Updated Feb 2026
Our Nidai Kitetsu replicas are forged from 1045 carbon steel, a medium-carbon alloy widely favored for collectible sword reproductions. This steel grade offers a strong balance between hardness and flexibility — hard enough to hold a visible hamon temper line along the edge, yet resilient enough to resist brittleness during handling or display mounting. Compared to stainless steel wall-hangers, 1045 carbon steel has a more authentic feel and weight, giving the replica a presence that closely mirrors a traditionally forged Japanese blade. It does require periodic oiling to prevent oxidation, which many collectors consider part of the rewarding ritual of sword care.
