Jade Serpent | Hadori-Polished & Clay-Tempered T10 Steel Katana with Half-Rayskin Saya

A blade that moves with a silent, hypnotic grace, the Jade Serpent Katana is a tribute to the guardian spirit of the wild. Its soul is the formidable T10 steel blade, clay-tempered and Hadori-polished to produce a genuine hamon that mirrors the serpent's fluid motion. The sword's true spirit is captured in the Koshirae—a full set of brown-finished brass fittings, intricately detailed with a coiling serpent theme. Wrapped in a noble jade-green silk ito and housed in a unique half-rayskin saya, this is a sword of profound beauty and deadly elegance.

Why Choose the Jade Serpent?

• Exquisite Hadori Polish: The blade is finished with a traditional Hadori polish, which artfully whitens the hamon, making the temper line stand out with dramatic, misty beauty against the steel.
• Intricate Serpent-Themed Brass Fittings: The heart of this sword's design lies in its full set of brass fittings (tsuba, fuchi, kashira), all featuring a detailed, coiling serpent motif. The antique brown finish gives these pieces a timeless, heirloom quality.
• The Power of T10 Steel: A Real Hamon Blade: At its core is a formidable blade forged from tough T10 tool steel. The blade is differentially hardened using a traditional clay-tempering process, creating a genuine hamon (temper line) for a razor-sharp edge and a resilient spine.
• Unique Half-Rayskin Saya: The scabbard (saya) is a work of art in itself. The gloss-black lacquer is accented with a large panel of genuine, polished white rayskin (samegawa), a high-end feature that adds texture, luxury, and a stunning visual contrast.
