Product Details
The straight 28.5-inch blade is forged from 1045 carbon steel and clay tempered to reach 58 HRC hardness. A continuous hamon line runs along the spine side of the blade, creating a wave-like pattern etched into the steel surface. The double-edged spear point tapers to a clean symmetrical tip, and the chrome-finished steel carries a subtle contrast between the tempered zone and the polished edge.
The 10.25-inch handle is wrapped tightly in black cord, providing a textured grip that stays secure during handling. The cord wrapping follows a uniform horizontal pattern, and the pommel cap is finished in black with a brass-tone alloy ring that matches the accent bands found throughout the piece.
In place of a traditional tsuba, this design uses a flush alloy collar where the blade meets the handle shaft. The brass-tone rings at each joint section serve as both decorative accents and structural reinforcements, creating a striking black-and-gold color scheme across the entire assembly.
The saya is constructed from iron with a piano lacquer finish in deep black, featuring fine horizontal grooves cut into the surface for added visual texture. At 28.5 inches, the saya doubles as the extension shaft for the spear configuration - the handle section locks into the saya's open end to create a full 53-inch polearm. This expandable design sets it apart from a standard Black 1045 Carbon Steel Ninjato and gives collectors a two-in-one display option.
Fully assembled, the piece weighs 4.5 lbs and stretches 53 inches from pommel to spear tip. The all-black palette with brass accents gives it a sleek, understated look that works equally well mounted on a wall or standing in a vertical display rack. For collectors drawn to Clay Tempered Ninjato designs, this expandable spear variant offers a distinctive silhouette that stands out in any collection.
