This is Kokuryū — a classic clay tempered T10 katana forged for both performance and prestige. The blade features a visible hamon line created by differential hardening and finished with the shiage togi technique for a mirror-like polish.
Its fittings include a brass tsuba, fuchi, and kashira coated in real 24k gold and silver leaf, carved with intricate dragon motifs. The tsuka is wrapped in black leather over real ray skin, offering both grip and elegance.
The saya is a handcrafted masterpiece: lacquered over polished genuine ray skin and inlaid with hand-carved buffalo horn. With a full tang, real yokote, and authentic kissaki, this katana sword is fully functional and display-worthy.
