Product Details

The blade on this katana is ground from 1095 carbon steel and given a distinctive blue surface treatment that shifts from deep cobalt near the spine to a brighter tone at the edge bevel. A real hamon line is present along the ha, the result of a differential heat-treatment process that creates a visible temper line between the harder edge and softer body of the steel. The precision-finished edge and handcrafted construction are consistent throughout the 40.55-inch overall length. Collectors looking to expand into Blue Blade 1095 Carbon Steel Katana pieces will recognize the quality of steel and finish at this specification.

The tsuka is built over a full tang core and wrapped in PU white samegawa, which provides a firm, slightly textured foundation beneath the ito. Over that sits a dark blue cotton cord in a traditional diamond-pattern tsuka-maki, leaving the white samegawa diamonds visible between each crossing. The wrap is snug and uniform from habaki to kashira, giving the handle a clean, symmetrical profile at 1.259 inches in width.

The tsuba is cast alloy in a dragon theme, finished in a black-and-gold two-tone palette. The outer ring carries finely detailed dragon relief work in matte black, while the interior oval reveals a warm gold surface that frames the nakago-ana. Matching fuchi and kashira fittings in silver-tone metal tie the handle assembly together and provide clean transitions between each component.

The saya is shaped from hardwood and finished with a premium natural lacquer that produces an iridescent teal-to-silver surface. The shifting color across the length of the saya changes with the angle of light, creating depth that complements the blue tone of the blade. A dark blue sageo cord is attached at the kurikata, matching the tsuka ito color and completing the coordinated blue-and-teal color scheme across the full koshirae.

Overall dimensions are 40.55 in length, 1.259 in blade width, and 0.275 in blade thickness, with a total weight of 2.8 lb. Packaged at 42.9 x 3.9 x 3.5 in and shipping at 3.3 lb. The coordinated blue nagasa, teal saya, and dragon tsuba make this a focused addition to any Blue Katana Weekly Deals lineup or standalone display collection.

Frequently Asked Questions

What steel and heat treatment does this blade use?
The blade is forged from 1095 carbon steel and receives a differential heat treatment that produces a real hamon line along the edge - visible proof of a harder edge zone against a softer spine.
How is the handle wrap constructed on this katana?
The tsuka uses a full tang core wrapped in PU white samegawa as the base layer, then covered in dark blue cotton ito in a classic diamond tsuka-maki pattern. The white samegawa shows through each diamond gap for a two-tone visual effect.
What gives the saya its teal iridescent appearance?
The hardwood saya is coated in a premium natural lacquer that creates a multi-tonal teal-to-silver iridescent finish. The surface shifts color with light angle. A matching dark blue sageo cord ties into the blue-teal color scheme.
