Spring Steel Blue Blade Katana with Skull Copper Tsuba in Marble Stone Saya - Collectible Samurai Sword

This katana features a 28.74-inch spring steel blade finished in a striking deep blue tone. The steel is heat-treated to 58 HRC, producing a visible hamon line that runs in an irregular zigzag pattern along the length of the blade. The blue finish contrasts sharply against the bright edge, giving the blade a dramatic two-tone look that catches light from every angle.

The tsuka measures 10.23 inches and is built on a full tang core. White PU samegawa wraps the handle base, overlaid with tightly wound black cotton ito in a traditional crosshatch pattern. The black-over-white layering creates a clean, high-contrast grip section that balances the darker tones found elsewhere on the sword.

At the junction of blade and handle sits a real copper tsuba cast in a sculptural skull design. The copper carries an antique gold patina with fine surface detailing on the skull's brow and jaw. This gothic-themed guard is a bold departure from conventional floral or geometric tsuba designs, making it a strong focal point among Traditional Katana pieces.

The 30.7-inch hardwood saya is finished in a grey-and-black marble stone lacquer that mimics natural granite. The textured surface is smooth to the touch yet visually rich, paired with a black-and-white braided sageo tied in a decorative knot at the kurikata. The overall effect places this scabbard alongside the finest examples in the Dark Blue Saya Japanese Samurai Swords collection.

With a total weight of 4.4 lbs and full tang construction, this katana is engineered for balanced display. The combination of blue-finished spring steel, skull-motif copper fittings, and marble stone saya creates a cohesive dark aesthetic suited for collectors who value bold design with quality materials.
