The jian is a double-edged straight
sword used during the last 2,500 years in
China. 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.
