Roiyaru Sanmai Katana


The Roiyaru Sanmai Katana from Thaitsuki is a hand-forged and folded katana and finished to the highest standards.


Thaitsuki is building the highest quality Japanese swords currently available. Thaitsuki  are true handmade swords that are produced in very low volume. Each component is hand crafted then fitted and assembled to create the finished katana or wakizashi. The end result is a sword that is a unique and functional work of art.

The Roiyaru Sanmai Katana continues Thaitsuki tradition, with a hand forged and folded 1024 layer high carbon steel blade and top grade hand crafted furniture and silver fittings.

The Roiyaru Sanmai Katana is handforged, folded, polished and sharpened entirely by hand, a rarity in this price range. This is simply one of the finest katana blades you will ever see. Silver handmade fittings and traditional white Japanese  silk ito over high grade ivory rayskin and double pegged tsuka with a traditional flower motif round out this stunning katana.

The half bo-hi blade has been heat-treated with the traditional clay-coating process and tempered. Its gunome hamon from this process is clearly visible along the edge.

The high carbon Japanese  steel blade is clay coated, heat treated, hand polished and sharpened. It is forged in the Koto style and hand folded with 1024 layers and features a half Bo-Hi in unokubi zukuri style. Differentially tempered, the edge hardness is 60 HRC and the body hardness is 35HRC for correct flex and superb feel when cutting.

Thaitsuki does not overlook the saya as part of the finished product and this saya is truly beautiful!  A two layer, hand rubbed white lacquered hardwood saya with silver Koiguchi enhances your investment. This katana can be completely disassembled for full maintenance.

This premium Japanese sword will appeal to the practitioner and high end sword collector.
