Introduction to tuoyuan katana:
– The blade is handmade using ancient sword forging methods. Fully handcrafted forging and fully handcrafted polishing.
-The blade is made of the steel improved by ourselves, differentially hardened and clay tempered, water quenched, and the hardness is approximately 56HRC.
– This blade has been tested to cut through everything that gets in its way, such as, it can easily cut through tatami mats. Sori (blade curvature) is specially designed to create leverage to perform the smoothest, cleanest cuts. The fuchi&kashira is cherry blossom theme made by ourselves, which is our best selling fittings.
– The real Hamon pattern is done in the same process as the traditional method. Edge hardening is using special clay to wrap the back of the blade and expose the cutting edge, heating it to a certain temperature and then putting it in water to quench it. This step is very demanding for a craftsman, and if he is not experienced, it will be difficult for him to succeed. Just this process creates out beautiful hamon. A special clay protects the back of the blade, and varying degrees of hardening of the blade causes the blade to bend, resulting in a perfect sori.
– This sword is made with yasurime. And the tsuka is handmade totally according to nakago, whose section is very neat and has no burrs. There is a mekugi on tsuka, the edges are made rounded. the rayskin used by tsuka is large particle rayskin, which is very expensive, and the ito is silk imported from Japan for wrapping. Expert finish on the end knot of the ito, to prevent uneven surfaces and bumps.
The chrysanthemum Tsuba of the sword is made of iron. The Fuchi and Kashira are made of high-quality cupronickel. The copper Habaki is a one piece construction. The tsuba and habaki fit very well with the blade, as you can see in the picture. Two red copper Seppas hold Tsuba in place to provide cushioning power when cutting.
