The Narrative
In the history of the imperial East, the sword was the definitive marker of a ruler’s resolve. The Royal Decree is a 40.5-inch masterpiece of Japanese-inspired metallurgy, hand-forged from elite T10 tool steel. This high-tungsten alloy is selected for its superior HRC potential and edge retention, allowing our master smiths to utilize the sacred ritual of clay tempering. This process creates a "Real Hamon"—a visible, crystalline transition line that signifies a hand-polished, razor-sharp edge supported by a more resilient, shock-absorbing spine. Featuring a full-tang construction and a precision-engineered Bohi (blood groove) for enhanced speed and audible feedback, this Katana is forged for the elite collector who demands a physical manifestation of authority.
The hilt (Tsuka) is a study in traditional luxury, featuring genuine ray skin (Samegawa) wrapped in deep navy silk (Ito), secured by dual bamboo Mekugi for unwavering stability during real-world cutting. Every fitting, from the high-quality alloy Tsuba to the hand-lacquered wood Saya, is meticulously finished to ensure a commanding presence in any elite armory. Accompanied by a protective black sword bag, The Royal Decree serves as the definitive benchmark for those who value the intersection of lethal functionality and the Sovereign Standard.

The Care
To preserve the hardened edge and the delicate Hamon of The Royal Decree, treat the T10 steel with absolute reverence. After any use or handling, the blade must be meticulously wiped with a soft, lint-free cloth or traditional rice paper to remove skin oils and environmental moisture. T10 high-carbon alloys require consistent vigilance against oxidation; we strictly recommend applying a light application of protective Choji oil or high-grade mineral oil every few weeks to maintain the mirror-polished finish. Store the sword in a dry, stable environment, safely within its wooden Saya, to ensure the spirit of the forge remains untarnished for generations.
