Clay Tempered Manganese Steel Katana with Real Hamon in Black and Silver Marble Saya - Grey Wrap

This full tang katana features a 28.74-inch manganese steel blade that has been clay tempered to achieve a genuine hamon - a distinctive wavy temper line visible along the cutting edge. The clay tempering process creates a harder edge at 58 HRC while maintaining resilience through the spine, and the chrome-finish blade surface highlights every detail of the hamon pattern. As part of the broader Clay Tempered Katana collection, this piece reflects the traditional differential hardening technique prized by collectors.;

The tsuka measures 10.23 inches and is built on a full tang hardwood core. PU black samegawa lines the grip surface beneath a tightly wound grey cord wrap, creating a secure hold with a clean, understated look. Dual menuki accent the handle, adding subtle texture beneath the wrapping.

At the junction of blade and handle sits a black alloy tsuba with an openwork design featuring flowing floral scrollwork. A gold-tone habaki and seppa frame the guard, creating a refined contrast between the dark openwork pattern and the warm metallic accents visible in the kashira and fuchi fittings.

The hardwood saya is finished in piano lacquer and displays a dramatic black and silver speckled marble pattern across its 30.7-inch length. A grey sageo cord is tied at the kurikata, matching the handle wrap and completing the cohesive grey-and-black color scheme throughout the sword.

At 40.94 inches overall and 4.4 lbs, this manganese steel katana is proportioned for display presence. The clay tempered blade, marble-finish saya, and floral openwork tsuba combine traditional construction methods with a distinctive visual identity suited for serious collectors.
