Blue Manganese Steel Katana with Dragon-Painted Saya and Red Samegawa in Black Cord Wrap

The blade of this katana is forged from manganese steel and features a deep blue finish that shifts in tone under different lighting. A bold zigzag hamon line runs the length of the edge, adding visual texture and contrast against the polished steel surface. The full tang construction extends through the handle, and at 41 inches overall, this piece carries real presence on any wall or stand.

The tsuka measures 11 inches and is built over hardwood, layered first with red PU samegawa for grip texture, then wrapped tightly in black cotton cord using a traditional diamond pattern. Small gold-tone menuki are set beneath the wrap, catching light between the cord gaps and adding a layer of detail that rewards closer inspection.

A round alloy tsuba separates blade from handle, finished in black with red radiating spoke cutouts that echo the red samegawa beneath the cord. The gold-tone floral habaki collar at the blade base provides a polished transition from steel to fittings, tying the warm accent tones together across the build.

The saya is crafted from hardwood and coated in premium natural lacquer that creates a glossy black base. Over this, a hand-painted dragon motif stretches across the lower half in white, gray, and red ink, depicting a coiling dragon with vivid red accents on its scales. This artwork transforms the scabbard into a standalone display piece. Browse more swords with similar aesthetic in our Black Leather Saya Japanese Samurai Swords collection.
