T10 Carbon Steel Katana with Real Hamon in Black Lacquer Saya with Red Lightning Stripe Design

The blade on this katana is crafted from T10 carbon steel, heat-treated and oil-quenched to produce a genuine hamon - that undulating temper line along the edge that collectors look for as a mark of traditional forging process. The hand-polished chrome finish brings out the steel's natural grain and makes the hamon clearly visible from hilt to tip. At 31 inches in blade length and 3 lbs overall, the proportions follow classic Japanese katana standards.

The tsuka is built around a full-tang core, wrapped first in black PU ray-skin to add grip texture, then hand-laced with black cotton ito in the traditional diamond pattern. The menuki hardware sits correctly beneath the wrap, and the overall handle construction reflects the layered build approach of koshirae-style assembly.

The silver-tone alloy tsuba carries a wave (nami) motif - a recurring theme in Japanese sword fittings that references water and natural force. The detail work on the surface gives it a hammered, hand-worked appearance rather than a flat stamped look, and the gold-tone habaki collar transitions cleanly between tsuba and blade.

The saya is where this katana makes its strongest visual statement. Black hardwood lacquered to a high gloss and painted with three diagonal red lightning stripes that run the length of the scabbard - bold, graphic, and immediately recognizable. The black sageo cord is laced through the kurigata in a traditional knot, ready for obi carry or wall display. For more designs in this color family, browse our Multi-colored Saya Katana selection.
