Black & Blue Katana - Manganese Steel Blade with Geometric Engraving, Black Hardwood Saya

The blade is the defining element of this katana. Forged from manganese steel and finished in deep blue, it carries a hand-applied geometric crackle pattern across the flat that catches light from every angle. Near the habaki, gold calligraphic text engraving adds a layer of cultural detail to what is already a visually complex surface. The blue coloration runs edge to spine, giving the blade a uniform, dramatic presence whether sheathed or displayed openly. For collectors exploring the Blue Blade Manganese Steel Katana category, this piece represents one of the more visually distinctive options available.

The tsuka is built on a hardwood core wrapped in black PU samegawa - an imitation ray skin base layer that adds texture beneath the ito. The black ito wrap follows a tight diamond pattern, consistent from collar to pommel, providing a secure hand position and a clean visual line. Full tang construction means the steel runs continuously through the handle, contributing to the sword's overall balance and structural integrity.

At the junction of blade and handle sits a gold-toned tsuba. The gold finish stands in deliberate contrast to the black handle wrap and blue blade, functioning as a warm chromatic anchor for the sword's overall palette. The guard's relatively compact, squared profile keeps the design grounded without overwhelming the more elaborate blade engraving.

The saya is lacquered hardwood in matte black, with a fine stippled surface texture visible in close-up. A circular gold kanji medallion is positioned near the koiguchi, providing the scabbard's single decorative accent. The black sageo cord matches the handle wrap, maintaining visual consistency across the entire mounted assembly.

At 41 inches overall length and 4 lbs, this katana is proportioned for full-scale display. Shipping weight is 5 lbs in a 43 x 4 x 4 inch package. Whether you're building a themed display or adding to a Blue Katana collection, the combination of geometric blade engraving, gold hardware, and all-black fittings makes this piece stand apart from standard single-color replicas.
