What steel grades are available in the hand-forged Japanese katana collection?
Updated Feb 2026
Hand-forged Japanese katana in this collection span T10 clay-tempered, Damascus fold-forged, Manganese Steel, 1060, and 1045 carbon steel with full-tang construction. T10 represents the premium traditional tier where clay-tempering creates the genuine hamon and the grain quality associated with the finest Japanese blade construction. Damascus provides the premium pattern steel tier where fold-forged layered construction creates the visually complex surface that single-steel grades cannot replicate. Manganese Steel provides the exceptional surface hardness tier that supports the most vivid color treatments. 1060 mid-tier and 1045 foundational-tier carbon steel provide genuine hand-forged construction at accessible price points. The grade range means that the hand-forged construction standard is accessible to collectors across different investment levels.
