Blade: The blade of the sword has been hand forged using the traditional six step method from ancient Japan. The blade has been constructed with a combination of high carbon and medium carbon steel. The high carbon steel is wrapped around the medium carbon steel giving the sword a hard jacket and cutting edge, while maintaining a soft flexible core. This combination of the soft core steel and hard cutting steel gives the sword an extremely hard cutting edge (as well as a very sharp cutting edge) while maintaining the swords flexibility. This combination of two steel types is called lamination, and is a painstaking process performed only by sword smiths. The smallest gap in the two steels can destroy the sword and smith has to start over again.
As with the lamination the Hamon and curve of the blade have been authentically created. The curve of the blade has been created as a result of the different steel used on the Ha and Shinogi. When the blade is quenched the sword is covered with a clay solution, except for the edge of the blade. The blade is then heated and quenched in water drawn from the spring of Longquan. Since the Ha cools much more quickly than the rest of the blade the molecules in the steel expand and force the softer steel to fold back.
The blade features a Bo-Hi (blood groove) for better balance and a audible feedback when the sword is swung. The Kissake is medium with a well defined Yokote. The sword has a massive tang to match the length of the blade.
Saya: The Saya is wooden with a black high gloss finish. The Kojiri and Koiguchi are oxidized copper with a simple, but elegant design. The Kurigata is wooden with a black cotton Sage-o.
Tsuba: The Habaki of the sword is one piece brass construction held in place by a copper Seppa. The Tsuba is oxidized copper in the Muromachi cut out style. The Tsuba is secured to the Tsuka with a copper Seppa.
Tsuka: The Tsuka is made of two pieces of wood laid over the massive tang. A ray skin Same has been wrapped over the wood, with a black cotton Ito over the Same. Two bamboo Mekugi secure the tang of the sword. Two dragon oxidized dragon Menuki are on each side of the Tsuka. The Kashira is also oxidized copper.
