How does blue blade treatment work on a 1060 carbon steel samurai sword?
Updated Feb 2026
Blue blade treatment on a 1060 carbon steel samurai sword is applied after the blade's primary grinding and polishing steps. The 1060 grade provides a surface quality suitable for blue treatment application, though not at the saturation level achievable on Manganese Steel. The controlled surface treatment process on 1060 creates a blue tone that ranges from medium to deep blue depending on the specific process and surface preparation quality. 1060's higher carbon content compared to 1045 means its surface after polishing is somewhat finer, contributing to better blue treatment uniformity than the lower grade. A blue blade 1060 samurai sword provides the vivid color treatment aesthetic at the mid-tier carbon steel price point, making the blue blade statement accessible to collectors who want the visual impact of blue treatment without the premium Manganese Steel price.
