What steel is used in the Yubashiri replica, and why does it matter?
Updated Mar 2026
The Yubashiri replicas in this collection are crafted from 1045 carbon steel, a widely respected material in the collectible and display sword market. The "1045" designation refers to a carbon content of approximately 0.45%, which places it in the medium-high range - enough to allow the blade to hold a defined edge geometry and develop a natural surface patina over time, both qualities appreciated by collectors. Unlike stainless steel, which can appear plasticky under display lighting, 1045 carbon steel has a deeper, more authentic visual character. It also responds well to traditional hand-forging processes, meaning the blade's profile and taper can be shaped with more precision than mass-stamped alternatives.
