1045 Carbon Steel Katana with Dark Blue Blade in Black-Blue Ito and Lightning Saya

The blade on this katana is forged from 1045 carbon steel and finished in a deep dark blue that shifts tone as light moves across its surface. Heat treatment and oil quenching produce a defined hamon line - the jagged, wave-like temper pattern visible along the edge that gives the blade its layered visual depth. The raging fire style hamon design adds drama without compromising the clean geometry of the grind.

The handle is built full tang, meaning the steel runs uninterrupted from tip to pommel. Black-blue ito wraps over PU white samegawa in a classic diamond-lozenge pattern, with small menuki fittings seated beneath the binding at each intersection. The grip is firm and proportional, shaped for extended display handling as well as formal presentation.

The tsuba is one of the most visually striking elements on this piece. Cast in white and gold alloy, it carries an all-over chrysanthemum relief - hundreds of small blossoms packed edge to edge across a rounded foil-shaped guard. Gold habaki and fuchi fittings transition cleanly between guard and handle, tying the warm metallic tones together.

The saya is hardwood finished in premium natural lacquer with a dark blue base coat and an overlaid crackled pattern that suggests lightning branching across a night sky. A white sageo cord is tied at the kurigata in a formal decorative knot, providing the only light-toned contrast on the scabbard and anchoring the overall black-and-blue color scheme.
