T10 Carbon Steel Katana with Hamon Blade in Dark Blue Cord Handle - Dragon Lacquer Saya

The blade is forged from T10 carbon steel and treated with a differential heat process that produces a genuine hamon line - the visible boundary between the hardened edge and the more flexible spine. The resulting chrome-finished nagasa runs the full 40.55-inch length of the sword and weighs in at 2.8 lb total, with a 1.259-inch blade width at its widest point. The raging fire style of the hamon gives the surface a turbulent, flowing character that shifts with the light. For collectors interested in the full spectrum of T10 craftsmanship, the Gold Blade T10 Carbon Steel Katana collection offers additional reference points.

The tsuka is built on a hardwood core wrapped in genuine black ray-skin (samegawa), which provides natural texture and grip even before the cord is applied. Dark navy blue cotton cord is then hand-wound in a traditional diamond pattern over the samegawa, with silver-tone menuki ornaments set into the wrap at two points. The dark blue sageo cord at the saya mouth ties the handle color into the overall design.

The tsuba is a standout component - a rounded, lobed silhouette in a black iron base with a gold-tone rim and engraved ornate scroll motifs on the face. A gold-tone fuchi collar separates the guard from the tsuka wrap, adding a warm metallic accent that anchors the blue-and-gold color palette running through the full koshirae.

The saya is crafted from hardwood and finished with multiple coats of premium natural lacquer in a black base. The dragon-theme decoration is applied across the full length of the scabbard in teal, gold, and muted blue tones - visible in the image as irregular organic shapes suggesting clouds or scales in motion. A dark blue sageo is secured at the kurigata, looping in a layered knot that mirrors the handle cord color. This is the kind of saya finish that makes the piece as visually compelling sheathed as it is drawn.

At 40.55 inches overall, 2.8 lb, and packaged in a 42.9 x 3.9 x 3.5 in box, this katana is sized and presented for serious display. The koshirae-style fittings - matched sageo, coordinated tsuba metalwork, and full-length lacquer saya - make it a cohesive collectible rather than an assembled set of parts.
