1045 Carbon Steel Katana with Clay-Tempered Chrome Blade in Copper Arabesque Saya with Gold Alloy Tsuba

This katana features a 28.5-inch T10 steel blade that has been clay-tempered to achieve a hardness of 60 HRC along the edge, producing a visible hamon line that traces the transition between the hardened cutting edge and the softer spine. The chrome-finish nagasa carries a bright, reflective surface that contrasts with the textured details of the fittings and saya. The blade is sharpened and built on a full tang foundation that runs the complete length of the handle.

The 10.25-inch tsuka is constructed from hardwood, layered with PU white samegawa to replicate traditional ray skin texture, and tightly bound in black cotton cord. Diamond-shaped gaps in the wrapping expose the white samegawa beneath, creating a clean geometric pattern. The handle terminates in a kashira that matches the gold-tone metalwork found on the tsuba and other fittings. For more options in this steel type, browse our 1045 Katana collection.

The tsuba is crafted from alloy in an oval, scalloped-edge shape with a gold finish. Its face features raised scrollwork and a textured central medallion, giving it a layered, dimensional appearance. The habaki collar sits in a matching copper-gold tone, tying the guard visually to the saya fittings.

The hardwood saya is the visual centerpiece of this piece. Its surface is finished in a deep copper-and-black arabesque lacquer pattern with flowing, organic scrollwork motifs. Near the koiguchi, the saya transitions into a striking white-and-black marble-spattered texture that extends partway down the length, creating a bold two-tone effect. A black sageo cord is tied at the kurikata for traditional carry presentation. The kojiri tip mirrors the copper arabesque pattern, unifying the saya design from end to end.

At 40.5 inches in overall length and 4.5 pounds, this katana has a presence suited for display stands, themed interiors, or collection showcases. The combination of a clay-tempered chrome blade, ornate copper-tone saya, and gold scalloped tsuba gives it a distinctive character among Black Carbon Steel Sword collectibles.
