The blade is forged from 1045 carbon steel, an alloy containing approximately 0.45% carbon by weight. This places it in the medium-high carbon range, which gives the steel enough hardness to hold a refined edge geometry while remaining tough enough to resist cracking during the forging and grinding process. For a display collectible, 1045 is a meaningful material choice—it produces a blade that looks authentic under close inspection and develops a natural patina over time that many collectors actively appreciate. It is a step above the mild steel or zamak alloys found in lower-tier anime merchandise, and its density gives the finished piece a realistic weight and balance.
