Features

8,000-Layer Hearth-Smelted Folded Steel
Hand-forged using refined furnace steel that is folded and hammered repeatedly across thousands of cycles to eliminate impurities. The resulting 8,000 composite layers produce exceptional shock resistance and a distinctive surface pattern.

Clay Differential Heat Treatment
Coated with traditional clay paste prior to quenching to create a hard 59–60 HRC martensite cutting edge while keeping the spine flexible (~45 HRC) to absorb heavy impacts without fracture.

13-Stage Japanese Tri-Color Hand Polish
Skillfully polished across thirteen stages of Japanese natural waterstones, producing a striking optical contrast between the frosty white temper line, the darkened body, and mirror-finished accents.

Genuine Buffalo Horn & Gilt Gold Appointments
The custom royal azure scabbard is fitted with high-density water buffalo horn at high-stress wear points, perfectly complementing the radiant gold-gilded copper guard and fittings.
