Crimson Tide | T10 Steel Clay Tempered Katana with Full-Wrap Rayskin Saya

A blade that surges with the power of a dark ocean, the Crimson Tide Katana is a masterpiece of dramatic contrast and luxurious craft. Its name comes from the striking crimson red rayskin (samegawa) on the handle, a flash of color against the deep black of the full-wrap rayskin saya. The sword's theme is the raging sea, captured in the ornate brass "Great Wave" fittings. At its heart is a formidable T10 steel blade, clay-tempered to produce a genuine hamon. This is not just a sword; it is the power of the ocean, captured in steel.

Why Choose the Crimson Tide?

• Luxurious Full-Wrap Black Rayskin Saya: The scabbard (saya) is a testament to ultimate luxury. It is fully wrapped in genuine, polished black rayskin (samegawa), an extremely rare and difficult craft that marks this as a true collector's grade sword.
• Striking Red & Black "Crimson" Handle: The handle (tsuka) features a powerful and iconic color combination, with a tight wrap of black silk ito over a core of vibrant, crimson red genuine rayskin. This provides a stunning visual and a secure grip.
• "Great Wave" Brass Fittings: The koshirae (fittings) are inspired by Hokusai's "The Great Wave." The intricately sculpted brass tsuba and fittings depict the powerful, crashing waves (Nami), giving the sword a deep artistic and cultural significance.
• The Heart of T10 Steel: A Clay-Tempered Blade: The blade is forged from high-performance T10 tool steel and features a genuine, beautiful hamon (temper line) created through the traditional clay-tempering process. This ensures a razor-sharp, hard edge with a resilient spine, ready for cutting practice.
