In the design of the Katai knives, wave-like shapes were used as inspiration. This can be seen in the shape of the blade and how the shape continues into the handle. The blade is entirely hand-forged in 5 layers of Japanese VG10 steel. The hammer finish on the blade is basically the same as the other series. However, it has undergone an additional finishing process using a very fine hammer. This method of processing is quite intensive, but results in a refined look with a completely unique appearance. The handle, in turn, is made from root wood. The wood is first filled with resin, then pressed, and subsequently shaped. Through this process, each knife is unique in finish, size, color, and wood structure.
