What steel grade and construction is used in the Michonne katana replica?
Updated Feb 2026
The Michonne katana replica in this collection is built from 1090 carbon steel with full-tang construction throughout. 1090 carbon steel is a high-performance blade grade with approximately 0.90% carbon content, which provides excellent blade hardness through proper heat treatment. The elevated carbon content of 1090 steel places it significantly above the common 1045 grade in terms of achievable hardness, delivering a blade character appropriate to a serious collectible. Full-tang construction means the steel blade runs from the kissaki tip through the complete handle body, confirmed by mekugi retention pins that secure the handle assembly to the tang. This construction distinguishes the replica from lightweight alloy or stainless steel prop replicas that cannot be properly heat treated and lack genuine blade character. The complete piece includes a proper handle assembly with wrapped handle and a wooden scabbard, creating a replica with the physical presence and weight of a genuine Japanese katana.
