T10 Carbon Steel Katana with Blue Lacquer Saya - Gold Vine Tsuba, Black-White Tsuka Wrap

The blade on this katana is forged from T10 carbon steel and hand-finished to reveal a natural hamon - the wavy temper line along the edge that results from the differential heat treatment process. Running 40.5 inches overall with a 1.26-inch blade width, the polished chrome-finish nagasa catches light cleanly, making the hamon's wave pattern easy to read. At 3.17 lb, the balance sits toward the guard, giving it the feel of a traditionally proportioned piece. For more T10 and high-carbon options, browse our full Replica Katana collection.

The tsuka is wrapped in traditional tsukamaki style using black cord over real white samegawa (ray skin), producing the signature diamond-window pattern visible in the photos. The contrast between the bright samegawa and black wrapping is clean and sharp - no loose ends, no uneven spacing. Copper fittings at the habaki and fuchi carry warm gold-tone tones that tie directly into the tsuba's color palette.

The gold-tone copper tsuba is the visual centerpiece of this koshirae. Its vine motif - flowing curved forms with gold and silver gilding detail - wraps around the oval guard in high relief. The result is an ornate but coherent design that reads as refined rather than busy. This guard style pairs naturally with the rich blue saya, and you can explore similar pieces in our Gold Printed Tsuba Japanese Samurai Swords lineup.

The saya is crafted from hardwood and finished with a deep navy blue natural lacquer that photographs differently depending on the light - sometimes pure dark blue, sometimes showing hints of shimmer in the lacquer surface. A black sageo cord is pre-tied at the kurikata, completing the traditional presentation. The lacquer finish is consistent and smooth with no visible brushwork or pooling.

This katana is a handmade koshirae-style replica weighing 3.17 lb with a 40.5 in overall length and packaging dimensions of 43.3 x 3.93 x 3.14 in. The full-tang T10 blade, gold vine tsuba, black-white tsukamaki handle, and dark blue lacquer saya work together as a cohesive set - detailed enough for serious collectors, visually striking enough to display on any wall or stand. Note: sword stand is not included.
