Hermit’s Swords are based on the Chinese double-edged one-handed sword, Jian. It is called one of the 4 major weapons in Chinese martial arts, along with the the gun (stick or employees), qiang (spear), and dao (sabre). In Chinese Sword folklore, the Jian is named “The Gentleman of Weapons”.

The Sharp Sword is the first non-NATO stealthy unmanned fight aerial automobile (UCAV). Constructed by Aviation Industry Corporation of China, with a lot of the work done by the Hongdu Aviation Industry Group, the Sharp Sword first flew in November 2013. Trying a bit like a mini-B-2 flying wing bomber, the UCAV has two internal bomb bays and a seemingly payload of about 4,400 pounds. Its engine is a non-afterburning WS-13 turbofan engine, with serpentine inlet to cover the engine from enemy radars (the primary Sharp Sword does not use a stealthy nozzle due to its expertise demonstrator status). It has a size of about 33 ft, and a wingspan of about 46 toes.

Through the years, around 170 Viking Ulfberht swords have been discovered throughout Europe, courting from 800 to 1000 Ad. The swords had been manufactured from metallic so pure, and crafted with such prime quality, that many say they have been centuries forward of their time. The Ulfberht was made with crucible steel, which has a carbon content 3 times greater than that of different metals of the time. It was believed that the expertise to create this metal was not invented for one more 800 or more years, through the Industrial Revolution.
