Thaitsuki – Roiyaru Sanmai Katana Limited Edition

This Limited Edition Roiyaru Sanmai Katana has a Koto-style blade which was skillfully handforged in the traditional sanmai laminated construction method which melds panels of forge-folded high carbon steel together to form a composite blade with an inner core of shock absorbing steel of 35 Hrc for resilience and an exterior of hardened 65 Hrc steel to ensure it has excellent edge retention and resistance to wear. The blade edge and its side panels are formed from folded T8 high carbon steel and this has been melded with a core and spine of folded T10 high carbon steel. After the folding process of its components the blade possesses a total of 1024 individual layers. A closer look at the blade will reveal the ripple-like patterning of the folded steel, as well as a faint line denoting where the hardened edge steel was forge-welded into form. Visible among this is also the wave-like hamon line which was created when the blade was clay tempered in the traditional manner to imbue it with a genuine hamon of hardened steel. The blade was completed with a high level of polish which was painstakingly executed to give it a fine sheen which highlights the beauty of its complex construction and its hamon. The half-bohi blade has been heat-treated with the traditional clay-coating process and tempered to an edge hardness of 60 HRc, an outer body hardness of 45 HRc and an inner body hardness of 30-40 HRc. Its waved hamon from this process is clearly visible along the edge. The blade is finished by being hand polished and sharpened.

The Habaki, Seppa and Menuki are of silver and the fuchi, and kashira are of blackened brass with silver flower accents. The tsuba of interwoven flora, is crafted from antiqued brass. The tsuka grip is wrapped with blackened rayskin and overlaid with woven ivory Japanese silk tsuka-ito with silver flowered menuki beneath.

The two-layer wooden Saya scabbard is coated with ivory white glossy lacquer. It has been fitted with silver accents, including a silver sayajiri at its tip. A sageo of  matching ivory cord is knotted to the Saya. The sword comes with a green silk sword bag. It does not include the original manufacturer’s production certificate.

PLEASE NOTE: There may be some minor to moderate cosmetic blemishing present on the scabbard and minor blemishing on the blade. These are handcrafted and hand-finished so minor cosmetic imperfections may be present.
