Seihikari Katana Sword: design and finishes

The name Seihikari (青光) evokes the mystical blue light that emanates from this exceptional blade. In Japanese, “sei” (青) refers to the deep blue of the night sky or the ocean, while “hikari” (光) represents pure, brilliant light. This name perfectly captures the essence of this katana, whose blue blade seems to capture and reflect a supernatural glow, symbolizing the quiet wisdom and serene strength of the accomplished warrior.

Its T10 steel blade has a deep blue hue that reveals a distinctive hamon obtained through differential tempering, a testament to the ancestral craftsmanship of Japanese sword smithing. The rounded, hollow guard (tsuba) in black alloy features delicately engraved leaf motifs, creating a striking contrast with the blade’s shine. The handle (tsuka) harmoniously combines solid wood and black imitation stingray skin, wrapped in black braiding (tsuka-ito) in a diamond pattern that ensures a firm and elegant grip. The menuki represent black dragons, symbols of power and protection, while the fuchi and kashira in plain black alloy complete this refined aesthetic. The blue lacquered solid wood scabbard (saya) harmonizes perfectly with the color of the blade, creating a set of remarkable visual consistency.
