Manganese Steel Katana with Hamon in Teal Ito, Chrysanthemum Tsuba & Black Lacquer Saya

The 28.74-inch manganese steel blade is the centerpiece of this collectible katana, ground and hand-finished to a hardness of 62 HRC. A clearly defined hamon line runs along the shinogi-ji, produced through the tempering process and visible under light as a flowing wave pattern - a hallmark of traditionally styled Japanese swordsmithing. The chrome-finished blade surface highlights the hamon's contrast against the polished steel, giving the nagasa a refined, display-worthy appearance. For those drawn to Long Katana construction, this blade's full tang build ensures structural integrity from tip to pommel.;

The tsuka measures 10.62 inches and is wrapped in teal silk ito over a foundation of genuine black rayskin (samegawa). The tight, diamond-pattern wrap creates evenly spaced menuki pockets and a comfortable two-handed grip. The real rayskin base provides both tactile texture and a traditional aesthetic layer beneath the ito - an authentic detail that separates this build from synthetic alternatives.

The tsuba is cast from brown alloy in a chrysanthemum theme, with gold and silver gilding applied to the floral relief patterns. The rounded form and warm copper-brown tone create a strong visual anchor between the teal handle and the polished blade. The habaki and seppa fittings are finished in a complementary gold tone, visible in detail shots and adding cohesion to the overall koshirae assembly.

The saya is shaped from hardwood and finished in a matte black lacquer, measuring 29.92 inches. The upper section is wrapped in pearl rayskin, adding a luminescent contrast to the deep black ground. Real horn is used for both the koiguchi (mouth of the saya) and kojiri (tip cap), materials chosen for their durability and period-appropriate character. A teal sageo cord is knotted at the kurigata, echoing the handle ito and pulling the full teal-and-black color palette together.

Overall dimensions place this katana at 40.55 inches in total length, weighing 2.8 lbs - proportioned for wall display or koshirae study. The koshirae-style construction, combining real rayskin, horn fittings, gilded tsuba, and lacquered hardwood saya, makes this piece a well-considered collectible for enthusiasts of classical Japanese sword furniture.
