What steel types are used in red and white katana?
Updated Feb 2026
This collection includes several distinct steel types, each with its own characteristics. 1045 carbon steel is the most approachable option — it forges cleanly, accepts a bright polish, and provides solid structural integrity for display mounting. 1060 manganese steel introduces slightly higher carbon content and added manganese, which improves grain refinement and gives the blade a bit more resilience during handling. T10 tool steel is a tungsten-alloyed carbon steel favored for clay tempering; the tungsten addition helps the steel retain hardness at higher temperatures during the quenching process, which produces a more pronounced and authentic hamon line. Folded Damascus steel blades are created by layering and forge-welding multiple steel billets, then folding them repeatedly to produce visible grain patterns called hada. Each steel type serves a different collecting priority, whether that's visual aesthetics, metallurgical complexity, or traditional authenticity.
