What steel is used in White Ichigo Katana replicas?
Updated Mar 2026
The pieces in this collection use either 1060 high-carbon steel, 1065 manganese steel, or clay-tempered 1065 steel, depending on the specific blade. 1060 carbon steel offers a reliable balance of hardness and flexibility, making it a common choice for display-grade replicas that still reflect genuine forging craftsmanship. 1065 manganese steel is slightly harder and produces a finer grain structure at the edge, which is why it's chosen for blades meant to have a more refined visual geometry. Clay-tempered 1065 goes a step further - the differential heat treatment creates a real hamon line along the blade, the same temper-line technique found in historically authentic Japanese swords. Each steel choice reflects the character of the blade being replicated, not just a generic production decision.
