Tamahagane Aomi Nami Katana

Tamahagane Aomi Nami Katana

The Tamahagane Aomi Nami Katana from the Daimyo series by Kaizen Sword Art is a tribute to the deep connection between the samurai and the sea. Aomi Nami literally means “blue wave” – a symbol of constant motion, control and inner strength. Like the waves, the samurai adapts, yet never loses his direction.

The Soul of the Samurai, Forged from Tamahagane
While many modern swords rely on industrial steel types, this katana returns to its origins. The blade is hand forged from traditional tamahagane steel, the legendary Japanese steel used for centuries in authentic samurai swords.

Tamahagane is known for its complex structure and lively character. Through repeated folding and differential hardening, a blade is created that combines exceptional sharpness with resilience. The result is a handcrafted katana with a soul – not a mass-produced weapon, but a sword with individual expression and depth.

Clay tempered heat treatment creates a natural choji hamon, recognizable by its flowing wave-like pattern reminiscent of foaming seas. This hamon is not only visually striking, but essential for balancing hardness and flexibility.

Shinogi-Zukuri Blade with O-Kissaki, the blade is crafted in the classic shinogi-zukuri style, the most respected geometry in Japanese swordsmithing. This form offers stability, cutting power and structural reliability.

The pronounced o-kissaki (large point) enhances the powerful character of this katana. Historically, the o-kissaki was often used during periods where cutting power and penetration were crucial.

With a subtle sori of approximately 1.9 cm, each cut follows a natural, flowing line. The absence of a bo-hi emphasizes the solid mass of the blade and contributes to a stable, authoritative cutting feel.

Tsuka and Koshirae – Control and Confidence
The tsuka is traditionally constructed in Ryugo style and fitted with genuine black ray skin (same). The dark blue Japanese cotton ito is extremely tightly wrapped, providing maximum grip and safety even during intensive use.

The mounting is robust and functional, featuring two mekugi for added security. The fuchi-kashira, menuki and tsuba are carefully selected and form a harmonious whole that highlights the understated elegance of the Aomi Nami theme.

The saya is finished in matte black lacquer and equipped with horn koiguchi and kojiri – a subtle reference to traditional luxury found in higher-class samurai fittings.
