Product Details

The blade is forged from 1090 carbon steel in a full-tang construction, running the complete length of the handle for solid one-piece integrity. A visible hamon line traces the edge in a flowing wave pattern, the result of differential heat treatment that creates the signature contrast between the hardened edge zone and the softer spine. Spanning 40.55 inches overall and weighing 2.8 lb, the proportions sit in classic katana territory. A highlight of this piece is the dragon engraving carved into the flat of the blade near the base - fine linework depicting a coiling dragon that rewards close inspection and sets this sword apart from plain-finished alternatives. Collectors interested in this steel grade can explore the full 1090 Carbon Steel Katana lineup for additional options.

The tsuka is built over the full-tang core and wrapped in PU white samegawa, a synthetic ray-skin analog that provides texture and grip foundation. Over that base, black cord is wrapped in the traditional diamond-gap pattern, with the white samegawa peeking through each opening to create a high-contrast black-and-white visual rhythm. The combination is clean and timeless - formal enough for display, structured enough for extended handling.

The tsuba is one of the most visually distinctive elements of this koshirae. Cast in alloy with a gold-and-black finish, it features a geometric design centered on two large oval leaf forms in polished gold, set against a dark background and surrounded by a ridged circular border with fine dot detailing. The overall effect reads as bold and ceremonial, drawing the eye immediately when the sword is presented hilt-forward.

The saya is shaped from hardwood and finished in a deep black lacquer that dries to a smooth, semi-gloss surface. The finish is consistent across the length of the scabbard and pairs directly with the black sageo cord, which is knotted at the kurikata in a traditional style. The all-black exterior of the saya creates a unified backdrop that makes the gold tsuba and white samegawa accents pop visually when the sword is fully assembled.

As a complete koshirae assembly, this katana presents a cohesive collector piece in the 1090 Carbon Steel Japanese Samurai Swords category - from the dragon-engraved, hamon-finished blade to the geometric gold tsuba and lacquered hardwood saya. Note that a sword stand is not included.

  • Full-tang 1090 carbon steel blade with a hand-finished hamon line and intricate dragon engraving along the flat, combining structural integrity with refined visual artistry.
