T10 Carbon Steel Wakizashi with Blue Blade, Dark Blue Ito & Teal Hardwood Saya

The blade of this wakizashi is forged from T10 carbon steel and treated to achieve a hardness of 62 HRC, with a full hamon line tracing the 28.74-inch nagasa. The steel has been finished with a deep blue surface treatment that shifts across the blade's surface, giving it a moody, layered appearance that reads differently under various lighting. The hand-finished edge runs the full length of the full-tang construction, keeping structural integrity from tip to pommel. Collectors drawn to Blue T10 Carbon Steel Wakizashi designs will recognize the distinct blue-to-violet gradient visible near the kissaki in the product imagery.

The tsuka measures 10.62 inches and is built over a real rayskin (samegawa) base in black, wrapped with dark blue ito in a traditional diamond-gap pattern that exposes the white samegawa beneath each opening. The wrapping is firm and even across the handle length, terminating neatly at both ends. Two gold-tone menuki are set beneath the ito, adding depth to the grip profile without disrupting the wrap tension.

The tsuba is cast from alloy in a black finish and shaped in an ornate scroll silhouette - an irregular, layered form that contrasts with the clean geometry of the blade and handle. Directly adjacent sits a gold-tone habaki collar that anchors the blade to the handle assembly and creates a deliberate color break between the dark handle and the blue nagasa.

The saya is constructed from hardwood with a matte teal finish and spans 29.92 inches. Three silver medallions stamped with a stylized family-crest (mon) motif are evenly spaced along the saya's face, providing decorative detail without breaking the smooth lacquered surface. A dark blue sageo cord is looped and knotted at the koiguchi in a braided arrangement. The overall saya color in the product image reads as a cool teal-blue with a slight metallic sheen under direct light - a distinctive finish for this Dark Blue Scabbard Wakizashi category.

Total assembled length is 40.55 inches at a weight of 4.4 lbs, packaged in a fitted box measuring 33.4 x 3.9 x 3.14 inches. The koshirae-style mounting, visible hamon, and coordinated blue-and-teal color scheme make this wakizashi a well-composed addition to a Japanese sword collection or display set.
