Product Details

The blade on this katana is ground from T10 carbon steel and finished with a clay-tempering process that produces a visible, natural hamon line running the length of the edge. Because the hamon is formed through actual differential heat treatment rather than acid etching, the pattern varies from piece to piece - wavy and irregular in the way traditional Japanese sword finishing produces. The chrome-polished surface of the nagasa catches light cleanly, letting the hamon stand out against the flat of the blade. For collectors interested in steel composition and heat treatment, this sits within the Natural T10 Carbon Steel Katana category.

The tsuka is wrapped in black ito cord over white PU same (ray-skin), forming the standard diamond-window pattern associated with traditional koshirae assembly. Silver-tone fuchi and kashira fittings frame the handle at both ends, and a pair of silver diamond menuki sit beneath the ito wrap at mid-grip. The construction is full tang - the steel runs continuously from tip through the handle without interruption.

The tsuba is cast in an ornate scroll pattern in aged black metal, with small gold floral accents scattered across the surface. The habaki separating the blade from the guard is finished in a light bone or cream tone, creating a subtle break between the chrome nagasa and the dark tsuba. The overall fittings palette runs black and silver with restrained gold detail.

The saya is crafted from hardwood and finished in a deep black piano lacquer that carries a speckled silver galaxy pattern across its surface - visible clearly in strong light and distinct from a plain lacquer finish. A black sageo cord is bound through the kurigata, and a small gold-tone menuki accent marks the cord fitting. The high-gloss finish gives the saya a polished, formal appearance that pairs well with the dark tsuka wrap.

Overall length is 41 inches with a shipping weight of 5 lbs. The sword packages in a 43 x 4 x 4-inch box. As part of the broader Japanese Long Sword category, this piece suits collectors drawn to authentic hamon aesthetics and cohesive black koshirae styling. Sword stand not included.

  • Blade forged from T10 carbon steel with clay tempering, producing a genuine hamon line along the edge - each sword carries a naturally unique temper pattern from the hand-finishing process.
  • Full tang construction runs the steel continuously through the tsuka, providing solid balance across the 41-inch overall length at 4 lbs - no hollow or rat-tail assembly.
  • Black hardwood saya finished in high-gloss piano lacquer with a speckled silver galaxy pattern, paired with a matching black sageo cord and a gold-tone menuki accent at the kurigata.
  • Black ito wrap over white PU same (ray-skin) creates the classic diamond-window pattern on the tsuka, accented with silver-tone diamond fuchi-kashira fittings for clean contrast.
  • Ornate scroll-theme tsuba in aged black metal with scattered gold floral inlays adds a refined finishing detail that complements the overall dark koshirae aesthetic.

Frequently Asked Questions

What steel and heat treatment does this katana use?
The blade is made from T10 carbon steel and clay-tempered to produce a real, naturally formed hamon line - not acid-etched. The hamon pattern varies slightly on each piece due to the hand-finishing process.
Is the tang construction full tang on this sword?
Yes. The steel runs continuously from the tip of the nagasa through the entire length of the tsuka. There is no rat-tail or partial tang - the full tang design gives the sword solid, consistent balance at 41 inches and 4 lbs.
What does the saya finish and tsuba design look like?
The saya is black hardwood with a high-gloss piano lacquer finish and a speckled silver galaxy pattern on the surface. The tsuba is cast in an ornate scroll motif in aged black metal with small gold floral inlay accents.
