Crimson Red 1045 Carbon Steel Katana with Full Tang Blade and Dark Red Lacquered Hardwood Saya

The crimson red blade on this katana is forged from 1045 carbon steel, heat-treated to 58 HRC. The full tang construction runs the entire length of the handle, and the steel carries a deep, saturated dark red finish that catches light with a warm metallic glow. At 28.3 inches, the nagasa offers traditional katana proportions with a 1.18-inch width that tapers cleanly to the kissaki. This piece fits well among other Darkred 1045 Carbon Steel Katana builds for collectors drawn to colored steel finishes.;

The tsuka measures 10.2 inches and is built on a hardwood core layered with black PU samegawa, giving the grip a textured foundation. Brown tsuka-ito cord is wrapped in a traditional diamond pattern over the samegawa, with gold-toned menuki peeking through the gaps. The combination of dark brown cord against black ray skin creates a subdued, earthy tone that pairs naturally with the crimson blade.

At the junction of blade and handle sits a black alloy tsuba with a round profile and detailed relief carving - floral and wave motifs are visible across its surface. A polished brass-toned habaki collar provides a clean transition between the tsuba and the blade, adding a warm metallic accent that echoes the gold menuki on the handle.

The saya is crafted from hardwood and finished with premium natural lacquer in a deep dark red with black wood-grain streaks running along its length. The glossy surface reveals subtle tonal variation under different lighting. A brown sageo cord is tied at the kurikata in a traditional knot, completing the scabbard's clean visual line. For those interested in similar color-themed swords, the Multi-colored Japanese Samurai Swords collection offers additional options.

With an overall length of 40.5 inches and a weight of 2.55 lbs, this crimson katana is proportioned for shelf or wall display. Every component - from the red-finished steel to the lacquered saya and carved alloy tsuba - follows a deliberate dark red and brown color scheme, making it a visually unified collectible piece built around a single bold palette.
