Nobutsuna katana is named in honor of Kamiizumi Nobutsuna (1508–1577), one of the greatest swordsmen of Japan's Sengoku period and the founder of Shinkage-ryū. Revered for his extraordinary swordsmanship, disciplined philosophy, and lasting influence on Japanese martial arts, Nobutsuna dedicated his life to perfecting both technique and character. Bearing his name, this katana pays tribute to his enduring legacy through a design that reflects balance, refinement, and traditional Japanese craftsmanship.
Forged from T10 high-carbon steel in traditional Maru-zukuri construction, the blade combines excellent cutting performance with a graceful and balanced form. Through traditional clay tempering, it develops a graceful Real Notare hamon, whose gentle undulating temper line flows naturally along the cutting edge like rolling waves. The differential hardening process creates a harmonious balance between a hard cutting edge and a resilient spine, reflecting the practical character of a traditionally forged katana.
The koshirae is centered around a Mokkō-gata brass tsuba adorned with blooming sakura motifs. The cherry blossoms symbolize the fleeting beauty of spring and the warrior's appreciation for impermanence. The fuchi and kashira, crafted from white copper (cupronickel), feature the Sakura Ishime design, combining delicate cherry blossoms with a finely textured stone finish. A polished brass habaki completes the mounting, complementing the warm tones of the fittings.
The tsuka is wrapped in black cotton ito over genuine white samegawa, providing a secure and comfortable grip while creating a timeless black-and-white contrast. The saya is finished in a distinctive White Speckled Lacquer, whose lightly textured surface evokes drifting snow or scattered cherry blossoms. A matching black sageo completes the koshirae, reinforcing the sword's balanced and elegant appearance.
