Description
Collectable Katana Golden Koi | Sanmai Steel Clay Tempered Blade | Polished Edge | Gold Gloss Lacquer Saya | Genuine Rayskin
This Golden Koi katana is crafted in Sanmai (three-layered) construction, featuring a hardened core edge between softer outer layers for sharpness and durability. The blade displays a subtle straight-grain pattern and a wavy temper line formed through clay tempering, with a classic ridge-style shape and an elegant long tip.
The fittings—including the tsuba, fuchi, and kashira—are solid copper with a blackened patina, decorated with koi motifs highlighted in gold and silver. The menuki beneath the handle wrap continue the koi theme. The handle is wrapped in red cotton over aged white ray skin, reinforced with diamond-patterned paper for grip and style.
The saya is made of hardwood with a gold-fleck lacquer finish, reinforced at the mouth with buffalo horn. A crimson cotton sageo is tied to the kurigata for secure carrying, completing the elegant and functional design.
Swords holder or stand sold separately.
