Manganese Steel Tachi Sword in Teal Wrap with Floral Hardwood Saya - Hamon Blade, Koshirae

The 28.74 in manganese steel blade is the centerpiece of this tachi, ground to a chrome polish and finished with a genuine hamon line running its full length. At 62 HRC hardness, the steel holds a hand-finished edge while the visible temper line adds authentic visual depth that separates this piece from simpler display reproductions. The blade profile follows classical tachi geometry - a gradual curve and elongated kissaki that read clearly even when sheathed. For collectors drawn to Hand Sharpening Tachi Swords, this build delivers refined craftsmanship in a full tang construction.

The tsuka measures 10.62 in and begins with genuine black rayskin (samegawa) as the base layer, providing natural texture and grip resistance under the wrap. Teal ito is wound in the traditional hishi-gumi diamond pattern, with white same nodes left exposed at regular intervals - a detail visible clearly in the close-up photography. The color combination of deep teal against white creates a striking, intentional contrast that anchors the sword's overall aesthetic.

The tsuba is cast alloy in a gold-black two-tone finish, featuring an ornate scroll design with raised floral clusters across the surface. The central opening is precisely fitted to the blade, and the seppa on either side maintain clean alignment with the handle and blade geometry. Gold-tone menuki and matching fittings on the tsuka reinforce the consistent hardware theme throughout the koshirae mounting.

The saya is shaped from hardwood and finished in matte brown lacquer, measuring 29.92 in. Near the kojiri, carved flower-theme decoration adds a hand-applied detail that softens the otherwise clean lacquer surface. A teal sageo cord is tied at the kurikata in a traditional looped presentation - matching the ito wrap color precisely and completing the visual coherence of the set.

At 40.55 in overall and 2.8 lb, this tachi sits in a balanced range suited to wall mounting or stand display. The koshirae-style construction - full matching fittings, rayskin handle, lacquered saya, and braided sageo - makes it a complete collector piece reflecting classical Japanese long-sword presentation. For those exploring Clay Tempered Tachi Swords and related tachi builds, this manganese steel example offers a polished entry point into the category with its detailed fittings and traditional proportions.
