The most famous sword in China is undoubtedly the Longquan Sword. According to historical records, it was the first iron sword, forged about 2,600 years ago by Ou Yezii, the great sword making master. Prior to that, swords had been made of bronze, while Ou was the person that figured out the method of smelting pig iron and forging it into a sword. Swords produced here are all called Longquan Swords.
