Chinese swords have a long history in China. Stone swords were used in prehistoric times.[citation needed] Bronze swords have been traced back to the bronze daggers of the Western Zhou period, but did not come into common use until the Eastern Zhou period. Bronze long swords suddenly appeared during the mid-third century BC. Later swords were made of iron or steel. These metals were wrought, never cast. Swords commonly reached a length of 70?C100 cm, although longer swords have been found.[1] Chinese iron swords were used in Japan from the third to sixth century AD, but were replaced with Korean and native Japanese swordsby the middle of the Heian eraChinese swords into two types, Jian (劍) and Dao (刀). Jian are dual edged and Dao are single edged. 1) Non-laminated bronze jian are well developed at this time. Appearance of the earliest laminated bronze jian where they utilize bronze with higher tin content for the cutting edges and bronze with lower tin content for the spine. It results in a sword with harder cutting edges and a more flexible spine to absorb shock2) Extensive use of copper sulphides as anti-corrosion coatings on the bronze jian3) Earliest iron and steel jian also appear, made by the earliest and most basic forging and folding techniques4) World's earliest book on alloys, "The Artificers' Record" is written, with an explicit statement on the percentage composition of the metals used in the Chinese bronze jian
