Features

Clay Tempered T10 High-Carbon Steel Blade
The Antique Copper Tachi blade is crafted from T10 high-carbon tool steel — a premium blade steel selected for its superior carbon content, fine grain structure, and exceptional capacity to hold a refined edge. Clay tempering is applied differentially across the blade — producing a hard ~60 HRC cutting edge and a resilient, shock-absorbing spine — then quenching locks in the natural Hamon temper line at the boundary between the two zones.

Special Craft Edition Hand-Grinding & Polishing
Following clay tempering, the blade undergoes a specialist hand-grinding and polishing process in the special craft edition finish — developing the full visual character of the T10 steel grain and revealing the natural Hamon temper line in complete clarity. The result is a blade surface of refined collector-grade quality.

Premium Authentic Black Ebony Scabbard
The scabbard (Saya) is crafted from premium authentic black ebony — one of the densest, hardest, and most visually prestigious natural woods in the world. Its deep near-black tone and exceptionally fine grain provide a commanding, refined backdrop for the warm antique copper fittings.

Antique Pure Copper Fittings with Classical Patina
All sword hardware — tsuba (guard), habaki, fuchi, and kashira — is cast in authentic pure copper and finished with an antique patina treatment that develops warm reddish-bronze tones with aged character. Antique copper fittings are a hallmark of classical Japanese sword presentation, evoking the aesthetic tradition of historical Japanese swordsmanship.

Full Tang Construction
The tang extends throughout the full 25cm handle length in the classical manner, anchored securely to ensure structural durability, authentic weight distribution, and the balance characteristics of a traditionally made Japanese tachi.

Maintenance

Handle the blade with clean, dry hands whenever possible. After handling, remove fingerprints and moisture using a soft cloth to prevent surface rust on the T10 high-carbon steel.

Apply a light coat of appropriate sword maintenance oil every 2-3 months to protect the blade from corrosion and preserve the clarity of the natural Hamon temper line.

Keep the black ebony scabbard away from extreme humidity fluctuations and heat sources to preserve the wood's natural deep finish and structural integrity long-term.

FAQ
