Product Details

The blade on this katana is forged from T10 carbon steel, ground to a 1.26-inch width and running a full tang through the handle core. A genuine hamon traces the hardened edge zone, the direct result of differential heat treatment applied during forging - not an etched or painted line. Hand-finishing brings out the contrast between the polished edge bevel and the satin flat, while wave engravings cut directly into the blade surface echo the piece's unifying design theme.

The tsuka is built over the full tang and dressed in authentic white samegawa - genuine stingray skin - before being wrapped in black cotton ito in the traditional diamond pattern. Amber-toned menuki accent pieces are visible beneath the wrap at the standard placement points, adding a detail visible in the imagery that ties back to the gold-tone fittings at the saya mouth.

The silver alloy tsuba is the visual centerpiece of the koshirae. Cast in a rounded mokkogata silhouette, both faces carry deeply worked wave scroll relief - cresting forms rendered with enough surface depth to catch directional light. A matching gold-tone habaki seats the blade at the tsuba, bridging the chrome blade finish and silver guard without visual interruption.

The saya is hardwood construction lacquered in a deep teal finish that photographs as blue-green depending on light angle - consistent with what you see in the product image. The sageo is black cord, knotted in a traditional wrap at the kurigata, and the saya collar is finished to match the overall dark accent palette.

Frequently Asked Questions

What steel and heat treatment does this katana use?
The blade is forged from T10 carbon steel with differential heat treatment that produces a genuine hamon along the edge zone. It is not etched or decorative - the hardness contrast is structural, visible as the lighter line separating the hardened edge from the softer spine.
What is the handle material and wrapping style?
The tsuka uses authentic white samegawa (stingray skin) as the base layer, wrapped in black cotton ito in a traditional diamond pattern. Amber-tone menuki accents are set beneath the wrap at standard positions, visible through the ito gaps on both faces.
What is the tsuba design and how does the saya color look in person?
The silver alloy tsuba features deep-relief wave scrollwork on both faces in a mokkogata outline. The saya is hardwood lacquered in a deep teal - it reads as blue-green depending on lighting - with a black sageo cord and matching dark collar fittings.
