1045 Carbon Steel Katana with Wave-Engraved Black Blade in Leather Saya - Black Tsuka

The blade on this katana is forged from 1045 carbon steel, heat-treated to 58 HRC, and finished in a deep black coating that runs from base to tip. At 28 inches, the nagasa carries a wave engraving along its length - a distinctive linear pattern that contrasts sharply against the polished silver edge bevel and the visible hamon line. The hand-finished edge runs cleanly to a well-defined kissaki point, with no rough transitions along the geometry.

The tsuka measures 11 inches and is wrapped in black cord using a traditional diamond-pattern binding over white same panels. The contrast between the dark cord and white menuki placements is visible throughout the wrap, giving the handle a classic two-tone appearance. Dual bamboo mekugi pegs lock the full-tang blade securely into the handle, maintaining structural integrity across the entire assembly.

A plain black iron tsuba sits at the junction of blade and handle. The unornamented design keeps the profile clean and avoids visual clutter - letting the wave engraving and hamon carry the character of the piece. The habaki collar fits flush against the tsuba with no visible gap.

The saya is constructed from black matte leather, measuring 28.5 inches. White contrast stitching runs along both edges of the scabbard body, and metal hardware - including slide buckles and a fixed loop fitting - is mounted along the upper section for carry or display mounting. The leather surface has a smooth, tight grain consistent with the matte finish specification. This build is part of our 1045 Katana range, which covers full-tang replicas across multiple styles and fittings.

At 39.5 inches overall and 3 lbs, this katana sits in a range well-suited for wall display, koshirae study, or as a centerpiece in a Japanese sword collection. The all-black color scheme - black blade, black tsuka, black iron tsuba, black leather saya - creates a cohesive, monochrome aesthetic that photographs well and holds visual impact on a display stand.
