Product Details

The blade on this katana is forged from T10 carbon steel, a high-carbon tool steel known for its edge retention and structural density. A clearly defined hamon line traces the length of the blade - the undulating temper boundary is visible along the polished chrome-finish nagasa, giving the sword its most distinctive detail. The precision-finished edge and clean geometry make this a standout piece among Marble T10 Carbon Steel Katana offerings.

The tsuka (handle) is built on a hardwood core wrapped in red PU samegawa, with black ito cord wound in the traditional diamond pattern over the top. Red diamond-shaped openings in the ito reveal the samegawa beneath, creating a layered black-and-red visual rhythm that runs the full length of the grip. Gold-toned menuki accents are set beneath the wrap at two points.

The iron tsuba follows an ornate scroll design with a red interior field and black cutout elements arranged in a circular pattern - bold and graphic, with clear visual weight that anchors the transition between blade and handle. The red-and-black color palette of the tsuba ties directly to the saya and tsuka, making the full koshirae feel intentionally coordinated.

The saya is hardwood lacquered in dark red with a textured finish - not a flat coat, but a surface with visible depth and grain-like patterning that shifts slightly in different lighting. A black sageo cord is knotted at the kurigata, and a small round black kojiri caps the tip. The overall saya silhouette is long, clean, and confident - a natural complement to the chrome blade when displayed together.

At 41 inches overall and 4 lbs, this katana is sized and weighted for display rather than use. Whether mounted on a wall or set on a stand, the black-red-chrome color story reads clearly from a distance. Collectors drawn to Red Japanese Katana designs will find the dark red saya and matched koshirae hardware a cohesive and visually striking combination. Stand not included.

  • Blade forged from T10 carbon steel with a visible hamon line - the wavy temper pattern runs the full length of the hand-finished edge, a hallmark of traditional Japanese sword craft.
  • Full-tang construction anchors the blade through the hardwood handle core, wrapped in black ito cord over a red PU samegawa (ray-skin) for a secure, traditional grip aesthetic.
  • The ornate scroll-themed iron tsuba features a bold red-and-black finish - circular cutout design creates strong visual contrast against the chrome-polished blade and black habaki.
  • Dark red hardwood saya is finished with a textured lacquer coat that catches light with depth and richness - black sageo cord ties off at the kurigata for a clean koshirae-style presentation.
  • Overall length: 41 inches, shipping weight: 5 lbs - proportioned for wall display or stand presentation in any Japanese-themed collection.
  • Complete koshirae set includes matched saya, sageo, tsuba, and tsuka - stand not included.
