Damascus Steel Katana with Blue Blade, Gold Alloy Tsuba & Black Hardwood Saya

The blade is the centerpiece of this katana - a 27.5-inch full-tang Damascus steel construction finished in a deep, graduated blue that shifts in tone along the length from spine to tip. Clay tempering produces a visible hamon line where hard and soft steel meet, and the 60 HRC hardness delivers a refined, hand-finished edge. A single bo-hi groove channels down the flat, lightening the overall feel and giving the blade a crisp, defined silhouette against any background.

The gold-toned alloy tsuba is the visual anchor of the fittings. Cast with engraved floral and geometric motifs on both faces, its irregular organic outline stands apart from standard round or square guards. The matching gold-accent koiguchi and kojiri on the matte black hardwood saya continue that design language the full length of the 30.3-inch scabbard, creating a consistent decorative thread from guard to tip.

The 10.2-inch handle is built on a hardwood core wrapped first in genuine white rayskin - the texture of which locks the outer layer in place - then covered in tightly wound black cord in the classic diamond-lozenge pattern. The result is a handle that sits firmly in hand without shifting, with the rayskin nodes just perceptible through the wrap. A black sageo cord exits the kurikata loop, finished with a small cluster of deep red beads that provide a deliberate accent against the all-black saya.

At 41.5 inches overall and 2.8 lbs, the proportions reflect a standard tachi-length katana. The full-tang construction means the steel runs uninterrupted from blade tip through the handle core, giving the piece structural integrity that display-only alternatives lack. The matte black saya surface absorbs light cleanly, making the gold fittings and blue blade stand out with minimal visual competition.

This katana suits a collector drawn to bold color work and ornate metalwork equally - the blue blade and engraved gold fittings read as a coherent aesthetic choice rather than independent add-ons. Displayed on a stand or resting in its saya, the piece carries the visual weight of a serious addition to any Japanese sword collection.
