Tsuru no Same-Koshirae | T10 Clay Tempered Katana with Full-Wrap Rayskin Saya

A sword that embodies the spirit of the samurai, the Tsuru no Same-Koshirae is a masterpiece of Japanese craftsmanship. Its name tells its story: Tsuru (鶴), the sacred Crane, is exquisitely sculpted in the brass fittings, a symbol of nobility and longevity. The Same-Koshirae (鮫拵) describes its ultimate luxury—a full mounting, from tsuka to saya, wrapped in polished black genuine rayskin. The blade within is a masterpiece of clay-tempered T10 steel, revealing a vivid and authentic hamon. This is not just a sword; it is a collector's grail.

Why Choose the Tsuru no Same-Koshirae?

• The Ultimate in Luxury: Full-Wrap "Same-Koshirae" Saya: The scabbard (saya) is the sword's most breathtaking feature. It is fully wrapped in genuine, polished black rayskin (samegawa). This extremely rare, difficult, and luxurious craft is known as "Same-Koshirae" and is a hallmark of a true heirloom-quality sword.
• The Pinnacle of Forging: Clay-Tempered T10 Steel: This blade is forged from high-performance T10 tool steel and then traditionally **clay-tempered** to produce a genuine, vivid hamon (temper line). This process creates an incredibly hard, razor-sharp edge (approx. 60 HRC) while maintaining a resilient spine.
• Master-Crafted "Tsuru" (Crane) Brass Fittings: The sword's theme is the Crane (Tsuru), a revered symbol in Japan for longevity, luck, and nobility. This is brought to life in the stunning, finely detailed brass sculptures on the tsuba, fuchi, and kashira.
• Classic Black & White Handle: The handle (tsuka) is built in the classic style for both beauty and function, featuring a traditional wrap of black silk ito over pure white genuine rayskin (samegawa), providing a superb grip and a timeless aesthetic.
