T10 Carbon Steel Katana with Hamon in Gray Saya - Gold Peony Tsuba, Gray Ito Wrap

The blade on this katana is forged from T10 carbon steel and hand-finished to a bright chrome polish, with a distinct hamon line tracing the edge from kissaki to habaki. That temper line - visible in natural light as a cloudy wave pattern along the steel - reflects the heat-treatment process applied to the nagasa, resulting in a hard edge and a more resilient spine. The blade measures 40.5 inches overall and 1.26 inches at its widest point, with a weight of 3.17 lb that gives the piece a grounded, purposeful feel in hand.

The tsuka is wrapped in gray cotton ito in a traditional diamond pattern over what the build calls PU samegawa - a synthetic ray-skin underlayer that adds grip structure beneath the braid. Bronze-tone menuki fittings are set into the ito at intervals, visible between the diamond gaps and adding both visual interest and hand-feel texture. The gray ito continues the sword's cool monochrome palette from handle to saya.

Separating tsuka from blade is a gold-tone bronze tsuba in a peony theme. The casting features openwork cutouts framing a central floral relief - petals and curving stems worked into the metal surface in a style consistent with traditional koshirae fittings. The warm antique-gold finish of the tsuba reads as the single accent color against the otherwise gray-and-silver palette of the sword. If you're building a display around Japanese floral motifs, the Gray T10 Carbon Steel Katana collection includes additional pieces in this color family.

The saya is hardwood finished in a matte gray lacquer with a marble-style surface texture - light and dark gray tones blending across the scabbard in an irregular stone-like pattern. A gray sageo cord is knotted at the kurigata, matching the ito wrap and completing the coordinated gray colorway. The matte finish keeps the saya from reflecting light, which makes the polished chrome blade stand out more sharply when the sword is drawn.

At 40.5 in overall with a 1.26 in blade width and 3.17 lb total weight, this katana is built to full samurai proportions and carries the heft of a properly constructed replica. Each piece is individually handcrafted, so minor variation in hamon pattern and lacquer texture is expected. Sword stand not included. For collectors drawn to gray-toned koshirae and classic floral fittings, this piece pairs well with pieces from the Gray Samurai Armor collection.
