The blade is crafted from manganese steel, a medium-carbon alloy that balances hardness with workability - making it well-suited for display-grade collectibles that need to hold a clean, polished edge over time. Manganese steel is harder than mild decorative steel but more forgiving to finish than high-carbon tool steels, which is why it appears frequently in quality anime collectible blades. The tanto profile itself - with its angular, chisel-like tip - is ground to reflect the classic Japanese short-blade geometry that defined the form during the Kamakura and Edo periods.
