Description
KSA “Jiang” Series Katana – Naoshige | Hand-Forged T10 High Carbon Blade | Clay Tempered with Real Hamon | Full Tang | Sashikomi Polish | Hand-Fitted Fittings | Genuine Rayskin | Authentic Kissaki Geometry | Brown Ishime Saya | Tight-Fitted Tsuka Core | Martial Arts Practice
Naoshige is named in honour of Nabeshima Naoshige (鍋島直茂, 1538–1618), an influential Sengoku-period warrior and statesman who played an important role in Kyushu and helped lay the foundations for Nabeshima rule in Saga. Known for his military experience, discipline, and strategic judgement, Naoshige became one of the most important figures of his era. This katana bears his name as a tribute to his resilience, composure, and martial spirit.
The blade is hand-forged from T10 high-carbon steel and traditionally clay tempered to produce a genuine Choji Hamon through differential hardening. Finished with Sashikomi polish, the blade presents a refined, traditional appearance while allowing the natural hamon to remain clearly visible. Its full-tang construction and authentic kissaki geometry provide both structural reliability and a more traditional Japanese sword profile.
The koshirae features a black iron tsuba with an openwork wheel motif, paired with darkened cupronickel Sakura Ishime fuchi-kashira. The tsuka is tightly wrapped in black cotton ito over genuine white samegawa, creating a strong monochrome contrast while providing a secure and comfortable grip.
A Brown Ishime saya adds warmth and texture to the mounting, while the black sageo brings the overall composition together. The restrained combination of brown, black, and white gives Naoshige a mature, disciplined appearance that reflects the character of its namesake.
