Product Details

The blade on this katana is forged from T10 carbon steel and treated to develop a genuine hamon line - the jagged, frosted temper pattern visible along the lower edge of the blackened spine. The contrast between the dark blade body and the bright hamon detail gives it an immediately striking profile. At 41 inches overall and 3 lb, the full tang blade carries real presence as a Traditional Katana collector piece.

The tsuka is wrapped in teal ito cord over a foundation of real white samegawa (ray skin), creating the diamond-pattern window effect clearly visible in the detail shots. The 10mm cotton cord wrapping provides both grip texture and visual depth, and the teal color reads as a deep blue-green that anchors the entire color story of the sword.

The black iron tsuba is cast with an open geometric cutout motif - flower-form apertures that lighten the guard visually while maintaining structural integrity. Gold-tone seppa washers on both sides of the tsuba provide a precise fit between guard and blade, adding a touch of warm contrast against the black iron.

A teal braided sageo cord is knotted through the kurigata of the black hardwood lacquer saya, finishing with a distinctive tassel that echoes the ito wrap color exactly. The saya itself is finished in smooth black lacquer over hardwood, protecting the blade and completing the sword's clean, unified aesthetic.

Frequently Asked Questions

What steel and hardness does this katana blade use?
The blade is forged from T10 carbon steel and heat-treated to develop a real hamon line along the edge. The darkened spine contrasts with the polished temper zone, which is a hallmark of a genuine differential heat treatment process.
Is the ray skin on the handle real samegawa?
Yes - the tsuka uses real white samegawa (ray skin) as the foundation layer beneath the teal ito wrap. The raised nodules of the ray skin grip the cord and prevent shifting, keeping the diamond-window pattern tight and consistent along the handle.
What is the tsuba design and how does the saya color match?
The black iron tsuba features an open geometric cutout pattern with flower-form apertures, accented by gold-tone seppa. The black hardwood lacquer saya pairs directly with it, while the teal sageo cord with braided tassel ties the guard hardware to the teal ito for a cohesive color scheme.
