KSA “Jiang” Series Katana – Takanobu | Vacuum Heat-Treated 9260 Spring Steel Blade | Premium Mirror Polish | Full Tang | Authentic Kissaki Structure | Hand-Fitted Fittings | Genuine Rayskin | Black Ishime Saya | Tight-Fitted Tsuka Core | Martial Arts Practice
Takanobu is named in honour of Ryūzōji Takanobu (龍造寺隆信, 1529–1584), the formidable Sengoku-period daimyō of Hizen Province. Renowned for his military strength and rapid expansion across northern Kyushu, he transformed the Ryūzōji clan into one of the region’s dominant powers and became widely known as the “Bear of Hizen.” This katana bears his name as a tribute to his resilience, commanding presence, and relentless determination.
The blade is crafted from 9260 spring steel and professionally vacuum heat-treated to achieve an excellent balance of toughness, flexibility, and impact resistance. The carefully controlled heat-treatment process provides consistent mechanical performance while minimising surface oxidation and decarburisation. Its full-tang construction further enhances structural reliability, making Takanobu a dependable choice for martial arts practice and practical cutting applications.
Finished with a Premium Mirror Polish, the blade presents a smooth and highly reflective surface that highlights its clean lines and precise geometry. The point is formed with an authentic kissaki structure, rather than a simplified cosmetic tip, creating a clearly defined transition into the kissaki and giving the blade a more traditional Japanese sword profile.
The koshirae is centred around an aged-brass Kiku-gata tsuba decorated with a dragon motif. The radiating chrysanthemum-shaped form creates a bold and balanced visual composition, while the sculpted dragon symbolises strength, authority, and rising ambition—qualities closely associated with Ryūzōji Takanobu’s powerful presence during the Sengoku period.
The fuchi and kashira are crafted from white copper cupronickel and decorated with the traditional Seigaiha wave pattern. The repeating waves represent continuity, resilience, and enduring strength, complementing the toughness and flexibility of the vacuum heat-treated 9260 spring-steel blade.
The tsuka is tightly wrapped in black cotton ito over genuine white samegawa, creating a timeless black-and-white contrast while providing a secure and comfortable grip. The mounting is completed with a Black Ishime saya, whose refined stone-textured surface offers understated elegance while helping conceal minor handling marks. A matching black sageo completes the restrained and dignified appearance of Takanobu.
