Product Details

The blade of this katana is forged from T10 high-carbon steel and clay-tempered to produce a genuine hamon - the undulating temper line visible along the 40.5-inch nagasa is not etched or simulated, but the result of differential heat treatment applied during the forging process. The steel exhibits a folded grain structure worked by hand, giving the chrome-finished blade surface a refined depth that sets it apart from machine-produced replicas. For collectors who prioritize authentic construction, this piece sits firmly within the T10 Japanese Sword tradition.

The tsuka is wrapped in dark blue ito over a black same (ray-skin) foundation, forming the classic diamond-pattern hishigami binding. The handle assembly is full-tang, with the blade extending the complete length of the grip for structural integrity. At 1.26 inches wide and a total weight of 3.17 lbs, the balance point is well-positioned for a piece of this length.

The tsuba is cast in a gold-toned chrysanthemum motif - the kiku (imperial chrysanthemum) design features radiating petals in a fluted sunflower arrangement with a raised central medallion. Menuki fittings in matching gold tone are set beneath the ito wrap, and the fuchi-kashira components carry the same warm metallic finish, creating a cohesive koshirae aesthetic across all hardware. This tsuba design is the defining accent of the Sunflower Tsuba Japanese Samurai Swords category.

The saya is constructed from hardwood and finished in a deep black piano lacquer - a high-gloss coat that reflects light cleanly and resists minor surface wear. Three gold tomoe roundels are inlaid at evenly spaced intervals along the scabbard body, each featuring the classic three-comma swirl associated with Japanese heraldry. The dark blue sageo cord is tied at the kurigata in a traditional knot, completing the color story that runs from handle to scabbard.

Overall dimensions measure 40.5 inches in blade length, 1.26 inches in width, and 0.275 inches in thickness. Shipping weight is 4.4 lbs. This katana is handcrafted in the koshirae style and intended as a collector piece - no sword stand is included.

  • Blade forged from T10 carbon steel with a visible real hamon line - the wavy temper pattern runs the full length of the 40.5-inch nagasa, a hallmark of traditional differential heat treatment.
  • Full-tang construction with dark blue ito wrapped over black same (ray-skin) - the diamond pattern hold is both visually striking and provides a secure, balanced grip at 3.17 lbs total weight.
  • Gold-toned chrysanthemum tsuba adds a classical Japanese kamon motif - the fluted petal design and imperial flower theme reference centuries of samurai heraldic tradition.
  • Black hardwood saya finished in high-gloss piano lacquer, accented with three gold tomoe medallions along the scabbard body - a bold contrast against the dark blue sageo cord.
  • Hand-finished by experienced swordsmiths using time-tested forging techniques - the T10 steel blade delivers a precision edge with visible folded grain structure throughout.
