Is the Demon Slayer Kokushibo sword a genuine Japanese sword collectible?
Updated Feb 2026
Yes - the Kokushibo sword replica in this collection is built to genuine Japanese sword collectible standards rather than being a costume prop or decorative piece. The blade is forged from 1045 carbon steel with full-tang construction running from the distinctive multi-bladed tip profile through the complete handle, secured by a mekugi retention pin. The distinctive visual design of Kokushibo's Nichirin blade from Demon Slayer - the multiple blade-like protrusions along the main blade edge and the pink-and-maroon color treatment - is represented in the replica's blade profile and finish. As an anime replica collectible, the piece is produced to capture the essential visual character of the character's weapon design while using materials appropriate to a serious collectible rather than a plastic or resin prop. Demon Slayer sword replicas are among the most actively collected anime sword designs currently, and the Kokushibo piece is one of the most distinctive within the series due to its unusual multi-blade profile.
