What steel grades are used in these Zanpakuto replicas?
Updated Mar 2026
The replicas in this collection are forged from high-carbon steel ranging from 1045 to 1065 manganese steel, depending on the specific piece. 1045 carbon steel offers a solid balance of density and workability suited to display-grade construction. 1060 carbon steel steps up the hardness and is commonly used where a more refined finish is desired. 1065 manganese steel, used in pieces like the Nozarashi and Sode no Shirayuki replicas, is particularly well-suited for clay-tempering processes that produce a visible hamon along the blade's surface. Each grade is chosen to match the visual and structural expectations of the character's blade rather than applying a single material across the entire lineup.
