This is cool

Via History Blog, archaeologists have unveiled an ancient bronze sword from the Warring States period (475-221 B.C.) that is still sharp and glossy after 2,300 years. The sword was discovered in tomb No. 18 in Xinyang city in China’s central Henan Province. It was found still snug in its scabbard inside a wooden coffin. 

The sword is a jian, a double-edged straight sword first documented in Chinese sources from the 7th century B.C. They were first made in bronze, then as Chinese metallurgy advanced, iron and steel. The Warring States period was a transitional era for the jian; swords of bronze, iron and steel have been found from the period. Bronze jian were made with different alloys, their properties employed to the weapon’s best advantage. The central spine and core of the sword was made with high copper content bronze, making it pliant but strong and less likely to break. The edges were made from high tin content bronze for optimal sharpness.

An amazing discovery, in amazingly good condition, and it's just too bad the little sword can't talk, as I'm sure it could tell some amazing tales.
