T10 Carbon Steel Katana with Real Hamon in Black Lacquer Saya - Gold-Black Flower Tsuba

The blade on this katana is forged from T10 carbon steel and clay-tempered through a hand-finishing process that produces a genuine hamon line running the full length of the cutting edge. The resulting temper pattern - visible as a flowing white mist against the polished chrome steel - is unique to each piece and stands as the clearest indicator of authentic differential hardening. At 40.5 inches overall with a blade width of 1.26 inches, the geometry follows classic katana proportions.

The tsuka is assembled over a full-tang core, wrapped in a traditional diamond-pattern black cord over a base of real white samegawa (ray skin). The texture of the ray skin shows through the open diamonds of the wrap, giving the grip both visual contrast and a secure non-slip surface. The fuchi collar is finished in gold-tone metal to match the rest of the fittings.

The tsuba is the visual centerpiece of this build. Cast in a gold-black colorway, it features dense floral scrollwork - hibiscus-style blooms and trailing vines - engraved across a darkened field. The habaki that seats against it continues the gold-tone theme, creating a cohesive transition between blade and handle. For collectors drawn to Flower Theme Scabbard Japanese Samurai Swords, this tsuba treatment is among the more detailed available at this price point.

The saya is built from hardwood and finished in premium natural lacquer with a black marble-speckled surface - irregular white flecks distributed across a deep black ground, giving each scabbard a slightly different pattern. The black braided sageo cord is secured with a decorative knot and tassel at the kurigata, completing the all-black-and-gold color scheme across the full koshirae.

At 3.17 lb. and shipping at 4.4 lb. in a 43.3 x 3.93 x 3.14 in. package, this piece arrives ready for display or collection. Collectors exploring Chocolate T10 Carbon Steel Katana variants will find this build shares the same steel and tempering approach while delivering a distinctly different aesthetic through its black-and-gold fittings and marble lacquer saya. Sword stand not included.
