Manganese Steel Katana with Koi Bronze Tsuba in Black - Scorpion-Print Hardwood Saya

The blade on this katana is forged from manganese steel and brought to a chrome-bright finish through hand-polishing, resulting in a clean, mirror-like surface that catches light along its full 41-inch length. The geometry holds a traditional shinogi-zukuri profile, tapering into a well-defined kissaki point. As part of our Natural-wood Manganese Steel Katana lineup, each blade is individually worked by experienced swordsmiths, so minor dimensional variations are inherent to the hand-production process.

The tsuka is wrapped in black ito over a PU black ray-skin (samegawa) base, using a traditional diamond pattern that locks securely without gaps. Gold-tone menuki figures are tucked beneath the wrap at two points along the handle, visible as subtle decorative anchors. The fuchi and kashira are finished in matching black alloy, keeping the handle assembly visually unified.

The tsuba is among the most visually distinctive elements of this build - a round bronze guard cast with a koi fish design in raised relief. Carved waves frame the fish on both faces, and the antique bronze finish gives the piece a sculptural weight that sets it apart from standard alloy guards.

The hardwood saya is lacquered black and carries a scorpion-print pattern running the full length of the scabbard body. The repeating motif is rendered in tonal contrast against the black ground - visible in texture rather than color. A polished silver-tone kurikata sits at the standard position, and a black sageo cord is attached for traditional carry. The saya interior is fitted to hold the blade securely with minimal play.
