Features

Three-Layer San Mai Folded Pattern Steel Blade
Forged using the traditional San Mai (three-layer) technique: a hard high-carbon steel core is clad between two softer outer layers. This construction combines superior edge retention with spine flexibility, and produces a distinctive wave-grain Damascus pattern across the blade surface that reveals the layered steel structure beneath. Each blade is uniquely patterned as a direct result of the forging process.

Differential Clay Tempering with Real Hamon
Clay tempered using classical Japanese techniques. The cutting edge is rapidly quenched to achieve superior hardness (~60 HRC), while the spine cools slowly to retain shock-absorbing elasticity, revealing an authentic, undulating natural Hamon along the blade.

Traditional Ray Skin (Same) Scabbard
The scabbard is covered in natural ray skin (same) — a traditional Japanese sword fitting material prized for its distinctive bumpy texture, natural grip enhancement, and visual authenticity. Ray skin scabbards have been a hallmark of premium Japanese sword presentation for centuries.

Full Tang Construction
The tang extends throughout the full handle length in the classical manner, anchored securely to ensure structural durability, authentic weight distribution, and the balance characteristics of a traditionally made katana.
