T10 Steel Full Tang Katana with Real Hamon in Green Ito - Gold Peony Tsuba & Black Lacquer Saya

The 28.74-inch manganese steel blade is the centerpiece of this koshirae-style katana, hardened to 62 HRC and finished to a bright chrome polish. A genuine hamon temper line traces the length of the edge, its irregular contour catching the light in a way that marks authentic heat-treatment work. The blade is sharpened and seats cleanly into a 29.92-inch saya with no lateral play.

The tsuka runs 10.62 inches and is built over a real rayskin (samegawa) foundation in black. Green ito is wound in the traditional diamond-gap style over the samegawa, with the pale texture of the skin visible through each opening - a detail that separates well-made koshirae from budget alternatives. The overall handle construction is firm, with no flex at the mekugi pin points.

The gold-tone alloy tsuba is one of the most visually distinctive elements on this katana. Cast in a peony relief pattern, the carved floral motif covers both faces of the guard with fine detail. The warm gold finish creates a deliberate contrast against the green ito and the dark blade, giving the sword a layered color story that reads clearly even from a distance. Collectors interested in similar gold-fitted pieces can explore the Gold T10 Carbon Steel Katana collection.

The black hardwood saya is finished in matte natural lacquer - a surface that resists minor handling marks better than high-gloss alternatives. Four circular flower medallions in dark green are set along the saya's length, continuing the floral theme from the tsuba. A green-and-white sageo cord ties off at the kurigata, with a braided knot that photographs well and holds its shape in display settings. This saya style is featured across the Flower Theme Saya Katana collection for buyers drawn to this aesthetic.

Total assembled length is 40.55 inches at 2.8 lb. The koshirae-style fittings, consistent green-and-gold color palette, and matte black saya with flower medallions make this katana a cohesive display piece for collectors focused on traditional Japanese sword aesthetics.
