1095 Carbon Steel Katana with Black Blade and Gold Lightning Hamon in Marble Hardwood Saya

This full tang katana features a 28.74-inch blade forged from 1095 carbon steel with a hardness of 62 HRC. The entire blade surface carries a deep black finish, set off by a vivid gold lightning-style hamon line that traces an irregular path from the habaki to the kissaki. The contrast between the dark steel and the bright gold line gives the blade a dramatic visual presence that catches light from every angle.

The tsuka measures 10.62 inches and is built over a core wrapped in black rayskin with red PU samegawa visible through diamond-shaped openings in the black cotton ito. Silver-tone fuchi and kashira cap both ends of the handle, while the menuki sit beneath the cord wrap for added grip texture. The construction extends the full tang through the entire handle length for solid structural integrity.

A round alloy tsuba in a rich gold tone serves as the centerpiece of the fittings. The guard features an intricate raised design of layered flowers, leaves, and branches that fan outward in high relief. The craftsmanship on this flower tsuba gives the sword a refined, ornamental character that balances the bold energy of the blade.

The hardwood saya stretches 29.92 inches and displays a striking marble pattern in swirled black and gold tones with a matte lacquer finish. A black sageo cord wraps around the kurikata, and a black kojiri caps the end of the scabbard. The marbled surface pattern on each saya is unique, making every piece one of a kind in this granite-finish 1095 katana line.

At 40.55 inches in overall length and 2.8 lbs, this katana balances well in hand and presents beautifully on a stand. The sharpened edge, gold lightning hamon, floral gold tsuba, and marble saya come together in a cohesive black-and-gold color theme suited for collectors who value bold visual design backed by quality carbon steel construction.
