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 Japanese Sword 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.
