The jian is a double-edged straight sword used during the last 2,500 years in China.
The first Chinese sources that mention the jian date to the 7th century BC during the Spring and Autumn Period. Historical one-handed versions have blades varying from 45 to 80 centimeters (17.7 to 31.5 inches) in length. The weight of an average sword of 70-centimeter (28-inch) blade-length would be in a range of approximately 700 to 900 grams (1.5 to 2 pounds).
There are also larger two-handed versions used for training by many styles of Chinese martial arts.
In Chinese folklore, it is known as "The Gentleman of Weapons" and is considered one of the four major weapons, along with the Gun (staff), Qiang (spear), and the Dao (sabre).
