T10 Carbon Steel Katana with Hand-Painted Dark Blue Saya - Real Hamon, Full Tang, Blue Ito

The blade is forged from T10 carbon steel and features a genuine hamon line along the edge - a visible result of the differential hardening process rather than an acid-etched imitation. The chrome-polished finish highlights the steel's surface texture and the subtle activity along the temper line. At 41 inches overall and 3 pounds, the full-tang construction ensures the blade runs the full length of the handle core, providing structural integrity for a piece built to be handled as well as displayed.

The tsuka is wrapped in dark blue cotton ito over a white ray-skin (samegawa) base. The traditional diamond-pattern wrapping creates evenly spaced nodes that expose the samegawa beneath, giving the grip both visual rhythm and a secure, textured feel in hand.

At the blade-to-handle junction, a gold-toned habaki fits snugly within the black iron tsuba. The tsuba carries an ornate scroll design with fine surface relief, and a copper fuchi ring adds a warm metallic contrast between the guard and the ito. The combination of black iron, gold, and copper tones gives the koshirae a layered, artisan quality.

The saya is crafted from hardwood with a dark navy lacquer base, then finished with a hand-applied splatter pattern of white, red, and blue - a technique that makes each scabbard visually distinct. A blue-purple braided sageo cord is knotted at the kurigata with a decorative knot and tassel, tying the entire color palette together.
