What steel grades are used for gold blade treatments in this collection?
Updated Feb 2026
Gold blade treatment and gold color configuration pieces in this collection are built from Manganese Steel and 1045 carbon steel with full-tang construction. Manganese Steel is the premier grade for vivid gold and yellow blade treatments: its exceptionally high surface hardness - significantly greater than standard carbon steel grades - creates a blade surface that accepts color treatments with maximum clarity and retains them with exceptional durability over time. The density of Manganese Steel's surface means the gold color reads with full saturation without the grain-related inconsistency that can affect lower-carbon grades. On a Manganese Steel gold blade, the warm golden tone is consistent across the full blade surface from base to tip. 1045 carbon steel provides the reliable foundational construction for gold blade and gold scabbard configurations that combine standard high-carbon steel construction with warm-tone aesthetics. 1045 full-tang katana with gold treatments have the correct weight and balance of genuine carbon steel construction while delivering the gold color presentation. All pieces feature full-tang construction confirmed by mekugi retention pins through the handle assembly.
