Blue Manganese Steel Katana with Lightning Hamon in Black Ito Wrap and Wire-Drawn Saya

This full tang katana features a 28.74-inch manganese steel blade finished in a deep blue tone and hardened to 58 HRC. A bold lightning-pattern hamon line runs the length of the blade in contrasting white, creating a dramatic visual that stands out against the blue steel. The kissaki tip carries the same jagged hamon motif, giving the point an aggressive, eye-catching profile.

The 10.23-inch tsuka is built on a hardwood core wrapped in white PU samegawa for texture, then bound tightly with black ito cord in a traditional diamond-weave pattern. Black menuki sit beneath the wrap, and the overall grip feels solid and well-balanced against the blade's weight.

At the junction sits a round iron tsuba with an openwork cross-style cutout, bordered by a gold-tone copper habaki collar. The contrast between the dark pierced iron and the warm gold accent adds a refined layer of detail to the sword's midsection.

The 30.7-inch hardwood saya is coated in a deep blue piano lacquer that mirrors the blade's finish. Across its surface, fine wire-drawn vein patterns branch outward in lighter blue, resembling lightning against a night sky. A black braided sageo cord wraps around the kurikata, completing the cohesive dark-and-blue color scheme. This katana belongs among the finest in any Blue Katana collection.

Measuring 41 inches in total length and weighing 4.4 lbs, this piece carries real presence on a wall mount or sword stand. The consistent blue-and-black palette - from blade to saya to handle - makes it a unified statement piece. For collectors exploring Blue Manganese Steel Japanese Samurai Swords, this katana delivers both craftsmanship and visual impact in equal measure.
