Manganese Steel Katana with Blue Blade, Wave Engraving & Black Lacquer Saya

The blade on this katana is forged from manganese steel and finished in a deep blue tone that runs the full length of the edge. Wave engravings are carved along the body of the blade, adding visual texture that catches light at every angle. A hamon line traces the edge, a detail that reflects the heat-treatment process and adds depth to the blue-finished surface. At 41 inches overall, the full-tang construction gives the piece a solid, balanced feel in hand.

The handle is built in koshirae style, with black ray-skin (samegawa) forming the base layer beneath black cord wrapping in a traditional diamond pattern. Gold-tone menuki are seated beneath the wrap, adding a subtle warm accent against the all-black hardware. The ivory-toned kashira at the base provides a clean visual break at the pommel end. If you're exploring other options in this finish family, the Blue Samurai Sword collection covers a range of blue-blade katana designs.

The tsuba is cast in black alloy and features chrysanthemum relief carving across its surface - a motif with deep roots in Japanese court and samurai tradition. The rounded form and detailed casting keep it proportional to the blade width without feeling heavy at the guard.

The saya is shaped from hardwood and finished in black lacquer, giving it a smooth, uniform surface. Black metal kojiri and koiguchi fittings frame the ends, while embossed decorative fittings along the body echo the saya's overall texture. A black sageo cord is tied at the kurikata for a complete presentation. For more pieces built around black hardware and finishes, see the Black Steel Sword collection.

This katana ships in a 43 x 4 x 4 inch package at a shipping weight of 4 lbs. Each piece is individually handcrafted, so minor variations in finish and fitting placement are part of the process. Sword stand not included.
