What makes S7 shock-resistant tool steel ideal for the Dragon Keep Tachi, and is it battle-ready?

S7 tool steel is an ultra-high-performance alloy engineered specifically for extreme shock resistance and high-impact applications. Heat-treated to 60 HRC, the blade achieves exceptional structural integrity—allowing it to flex up to 90° without permanent deformation and cut through iron targets without edge chipping or damage. Combined with a hand-forged ultra-high mirror polish, the Dragon Keep Tachi is 100% battle-ready and optimized for heavy Tameshigiri (target cutting).

How does the ultra-high mirror polish finish protect the S7 steel blade?

Beyond delivering a striking, museum-quality reflective sheen, the precision hand-forged mirror polish smooths out microscopic steel pores on the blade surface. This significantly reduces moisture retention and prevents surface oxidation (rusting), ensuring long-lasting blade protection while providing a crystal-clear reflection on display.

What details are featured on the scabbard (saya) and ornamental sageo cord?

The scabbard is crafted from solid wood finished in a subtle, gold-flecked black lacquer ("star-sprinkled" finish) that offers scratch and scuff resistance. It is paired with a high-friction, black-and-green woven sageo (ornamental cord) and antiqued copper dragon fittings, securing the blade firmly while offering a sophisticated, non-slip carry.

What are the dimensions and balance specifications of the Dragon Keep Tachi?

The sword measures 104 cm in total length with a 72 cm blade, a 26.5 cm handle, and a blade width of 3.2 cm. Weighing approximately 1.58 kg, its center of gravity is meticulously balanced by antiqued black-and-gold pure copper dragon fittings (including the tsuba, fuchi, kashira, and koiguchi), allowing fluid handling, quick directional control, and minimal wrist fatigue during form practice.
