Red Blade Katana in Manganese Steel with Black-Gold Chrysanthemum Tsuba and Red-Black Lacquer Saya

The blade is forged from high manganese steel and finished in a deep red surface treatment that gives this katana its defining visual identity. Running the full 40.5-inch length with a full tang construction, the blade carries a hand-finished hamon line along its edge where the polished silver cutting surface meets the red body - a detail the swordsmiths refer to as the raging fire style. The steel is treated to achieve consistent hardness and durability, and because each piece is individually handmade, minor variations in finish and fit are a natural part of the craft. Collectors who want to explore more options in this finish can browse the Red Blade Manganese Steel Katana collection.

The tsuka is built on a full tang core wrapped in red PU samegawa, then bound with black ito in a tight diamond pattern that exposes the red underlayer at each lozenge. The result is a black-and-red grip with real visual depth. A silver kashira caps the pommel end, and small menuki accents sit beneath the wrap for additional grip texture.

At the transition between blade and handle, the black iron tsuba makes an immediate visual statement. Its open-wheel silhouette features symmetrical cutouts around the rim, while a gold chrysanthemum mon anchors the center - a motif historically associated with imperial Japanese symbolism. The black body and gold inlay create a high-contrast pairing that holds up well against the red and black color scheme of the rest of the piece.

The hardwood saya is lacquered in a red-black finish with a mottled, textured surface that suggests depth without being uniform. A black-and-red sageo cord is tied at the koiguchi in a traditional knot, adding a final layer of authentic koshirae styling. The overall presentation is cohesive: every element from sageo to kashira follows the same red-and-black palette. For a broader look at this color family, the Red Katana collection offers additional styles in this range.

Overall length is 40.5 inches with a blade width of 1.26 inches and spine thickness of 0.275 inches. Total weight is 3.17 pounds. Each sword is handmade individually, so minor variation between pieces is expected. Sword stand not included.
