All swords produced by the family run Thaitsuki Forge are 100% handmade with the highest standards and attention to detail by Thaitsuki craftsmen and artisans who have served for years in apprenticeship under the master sword smith, Mr. Sivarat.

Each Thaitsuki katana and Wakizashi is created following proven traditional methods. From the perfectly wrapped Ito, to the handcrafted Kashira, Menuki, Tsuba and Fuchi, each piece is made with the highest quality materials by skilled craftsmen that specialize and take pride in their art.
The Habaki, Menuki, Fuchi and Kashira are handmade from quality silver. The Tsuka is skillfully wrapped with only the finest Japanese silk over genuine high grade ray skin.

The saya is built in two layers, with a hardwood outer layer and softwood inner layer contacting the blade with a genuine black horn Koiguchi. Each saya is hand crafted to custom fit it’s partnering blade, then finished with multiple coats of hand rubbed lacquer.

Each full tang blade is perfectly balanced and hand forged from only high grade, high carbon Japanese steel.

Every Thaitsuki sword comes with it’s own serial number and signed certificate from Thaitsuki Nihonto, so you can trace it back to when and by whom it was made. Because each sword is handmade and the fittings are handcrafted, no two swords will be ever be exactly alike. Each is a unique work of art.

It is a weapon suitable for practitioners and collectors. This katana can easily sever a 4″ thick bamboo with single stroke.

The Kumori katana continues Thaitsuki tradition in premium Japanese swords, with a hand forged, high carbon, Japanese steel blade and top grade hand crafted silver fittings.
