1045 Carbon Steel Katana with Brown Leather Saya - Blue-Black Sageo, Bronze Scroll Tsuba

The 29-inch nagasa is forged from 1045 carbon steel and heat-treated to 58 HRC, striking a balance between edge retention and flexibility. A visible hamon line traces the length of the chrome-finish blade, produced during the hardening process and left exposed on the polished surface as a mark of the forging craft. The full-tang construction extends unbroken into the handle, giving the piece its structural integrity. If you're building a collection around this steel grade, browsing 1045 Katana titles is a natural next step.

The 10.25-inch tsuka is built on a sturdy wooden core wrapped first in white polyurethane samegawa, then finished with dark blue cord in a traditional diamond-pattern braid. Gold-accent menuki sit beneath the wrap at evenly spaced intervals, visible through the diamond gaps and adding a warm metallic contrast against the deep navy cord.

The tsuba is cast from alloy in a bronze tone and features ornate scroll relief work across its full face - dense, curling botanical motifs that wrap around a textured center. A small koi-motif detail sits at the base of the blade opening, adding a secondary design layer that rewards close inspection. The bronze coloring reads warm against both the dark handle and the polished blade.

The saya is covered in matte brown leather, running 29.5 inches to match the nagasa. A braided blue-black sageo cord is knotted and draped at the kurigata, creating a vivid contrast against the warm brown ground. The matte finish keeps the saya from competing with the blade's polished surface, letting the color pairing do the visual work.

At 41 inches overall and 4.4 lbs, this katana is proportioned in full koshirae style and arrives sharpened. It is intended as a replica collectible and display piece, with the complete fitting set - tsuba, tsuka, saya, and sageo - assembled to present a cohesive traditional aesthetic.
