Features

Gomai (5-Piece Laminated Pattern Steel) Blade with Heavy 8.0mm Spine
The blade is traditionally hand-forged utilizing the revered Gomai lamination technique—combining five distinct sections of pattern steel and high-carbon steel forge-welded into a unified matrix. Built with a robust 8.0mm spine thickness, this advanced metallurgy pairs exceptional edge hardness with supreme shock-absorbing resilience.

Clay Tempered with Real Hamon
Differentially clay tempered by master smiths, rapidly quenching the cutting edge to achieve superior hardness (~60 HRC) while allowing the spine to cool slowly for shock absorption. This creates a distinct, naturally formed undulating Hamon temper line.

Genuine Pearl Rayskin Scabbard
The scabbard (Saya) is sculpted from solid hardwood and completely encased in authentic, select-grade pearl stingray skin (Samegawa). Prized for centuries by samurai armorers, pearl rayskin provides an intensely durable, bead-textured surface with a mesmerizing organic luster.

Antique Gold & Silver Plated Pure Copper Dragon Mountings
The Tsuba, collar, pommel, and menuki are sculpted from solid pure copper with detailed sea dragon motifs, accented with antique dual-tone gold and silver plating for an imposing regal aesthetic.

Full Tang Balanced Construction
The tang extends through the entire handle in the classical manner, fastened securely to ensure authentic weight distribution, balance, and lifelong structural integrity.

FAQ

What is Gomai steel construction?
Gomai (5-piece lamination) is an intricate composite forging method combining five layers of steel. This allows master smiths to optimize edge hardness (~60 HRC) while preserving core shock resistance.

What is the Sea Dragon symbolism?
In Japanese and East Asian lore, sea dragons represent control over the elements, prosperity, and powerful guardian warding against negative energy, making them one of the most revered motifs for collector swords.

Why is the blade thickness 8.0mm?
An 8.0mm thickness at the spine provides substantial heft, authentic historical rigidity, and a powerful visual profile suited for master-tier display swords.

Is the rayskin scabbard genuine?
Yes. The Saya is fully wrapped in authentic, select-grade pearl stingray skin (Samegawa), known for its natural granulated texture and centuries-long heritage in samurai armor and sword mountings.
