Product Details

The blade of this katana is forged from T10 carbon steel, a high-carbon material prized for its edge retention and structural integrity. The clay tempering process creates differential hardness between the edge and spine, and the resulting hamon - a naturally formed wave pattern along the edge line - is visible and unique to each piece. The blade runs 41 inches in total length at 1.259 inches wide and 0.275 inches thick, weighing in at 3 lbs, with a chrome finish that contrasts cleanly against the black koshirae. For collectors looking at the full range of Authentic Hand Forged Katana options, this piece represents a strong entry point in traditional construction.

The tsuka is built on a full tang foundation, ensuring structural continuity from blade through handle. PU black samegawa covers the core, providing a firm, textured base layer before the black cord wrap is applied in the traditional koshirae style. The wrap pattern is tight and even, offering both visual discipline and a reliable gripping surface during extended handling.

The tsuba is cast from black alloy in a plain, circular form. Its understated design keeps the visual weight balanced - nothing competes with the blade's hamon or the sageo's two-tone detail. The matte black finish is consistent with the overall color palette and sits flush against both blade and handle components.

The saya is constructed from hardwood and finished with a premium natural lacquer in deep black, providing durable protection for the blade during storage and display. The black-and-white braided sageo cord is knotted at the saya mouth in the traditional style, and its two-tone pattern is the only deliberate color contrast in the design - visible clearly in the product imagery. This cord detail gives the otherwise monochromatic presentation a focused point of visual interest.

At 3 lbs and 41 inches overall, this katana is proportioned for display and koshirae appreciation. The full koshirae assembly - lacquered saya, alloy tsuba, cord-wrapped tsuka, and clay tempered T10 blade - comes together as a cohesive collector piece rooted in traditional Japanese sword aesthetics.

  • Blade forged from T10 carbon steel, clay tempered for differential hardening, producing a genuine hamon line visible along the edge - a hallmark of traditional Japanese sword craftsmanship.
  • Full tang construction with a hand-finished edge, ground and polished by skilled artisans for a refined, consistent profile from spine to tip across the 41-inch overall length.
  • Black cord tsuka wrapped over PU black samegawa, delivering a firm, textured grip with consistent tension across the full handle length - functional and visually cohesive.
  • Black alloy tsuba with a clean, understated profile provides solid hand protection while maintaining visual balance between the blade and handle components.
  • Hardwood saya finished in deep black lacquer, paired with a black-and-white braided sageo cord that adds contrast and traditional styling to the overall koshirae presentation.
  • Total weight of 3 lbs with a 41-inch length and 1.259-inch width - proportions suited for display or handling practice by collectors and Japanese sword enthusiasts.

Frequently Asked Questions

What steel and heat treatment does this katana use?
This katana uses T10 high-carbon steel with a clay tempering process, which creates differential hardness between the edge and spine. The result is a genuine hamon pattern - visible on the blade - that confirms the traditional heat treatment was applied.
Is the blade full tang on this katana?
Yes, this katana features a full tang construction, meaning the steel runs continuously from the tip through the entire tsuka. At 41 inches overall and 3 lbs, the full tang design provides structural integrity throughout the handle assembly.
What are the tsuba design and saya finish details?
The tsuba is a plain circular black alloy piece with a clean, unfussy profile. The saya is hardwood finished in deep black natural lacquer, paired with a black-and-white braided sageo cord - the sole color contrast element in this all-black koshirae set.
