Inazuma means lightning — the sudden strike, the flash and the crack that follows. This katana earns the name twice: in the mirror-polished blade that throws light like a bolt across the sky, and in the low whistle the bo-hi draws from the air on every cut. It is a clean, sober sword that does its talking when it moves.
Forging & Steel
The blade is T10 tool steel, clay-tempered, mirror-polished and run through with a bo-hi groove. The clay laid on before the quench produces a genuine hamon — the temper line born in the quench — while the bo-hi removes mass to make the sword light, fast and balanced. Hard, sharp and sound-producing, it works as a practical cutting and training blade for committed beginners and reads beautifully on display. The mirror polish throws the hamon into sharp relief, so the temper line is easy to read along the edge.
Fittings
The furniture is restrained and solid. The tsuba is finely carved iron, the saya is solid lacquered wood, and the tsuka is wrapped in stingray fish leather with a two-tone tsuka-ito that lifts the sober blue-toned blade. Nothing here is loud; the appeal is in the balance, the polish and the clean lines rather than ornament.
