Spring Steel Katana with Black Raging Fire Hamon in Teal Ito Wrap and Skull Tsuba - Full Tang Collectible

This full tang katana features a 28.74-inch spring steel blade finished in a deep black coating with a dramatic raging fire hamon line running along the edge. Hardened to 58 HRC, the steel holds a refined edge and delivers a striking visual contrast between the dark spine and the bright, zigzag temper line. The blade profile is classic shinogi-zukuri, tapering to a clean kissaki that catches light at every angle. For collectors drawn to Black Steel Katana designs, this piece delivers bold character without compromise.

The 10.23-inch tsuka is built on a wooden core wrapped in white real rayskin for grip texture, then finished with teal cotton ito in a traditional cross-knot pattern. The color sits between dark green and deep teal, providing a sophisticated contrast against the black fittings. Gold diamond shapes of the rayskin peek through each wrap crossing, adding a subtle but intentional detail to the handle.

At the intersection of blade and handle sits an alloy tsuba in an antique bronze-black patina, featuring a detailed relief of skulls and coiled serpents. The design is sculptural and deeply carved, giving the guard real visual weight. A polished brass habaki collar seats the blade firmly and bridges the dark tones of the tsuba with the bright hamon line below.

The 30.7-inch saya is constructed from hardwood and fully wrapped in a textured black material with a fine diamond-knurl pattern, secured with a black sageo cord tied in a traditional knot. The surface has a matte tactile finish that contrasts with the glossy brass kuchiganae at the mouth. This scabbard design gives the katana a distinctly modern, understated look while protecting the blade during display.

Overall length comes in at 40.94 inches with a total weight of 4.4 lbs, making this a substantial piece suited for shelf or wall display. Every fitting - from the teal ito to the skull tsuba to the leather-wrapped saya - works together to create a cohesive dark theme.
