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 BCE, during the Spring and Autumn period; one of the earliest specimens being the Sword of Goujian. Historical one-handed versions have blades varying from 45 to 80 centimeters in length. The weight of an average sword of 70-centimetre (28-inch) blade-length would be in a range of approximately 700 to 900 grams. There are also larger two-handed versions used for training by many styles of Chinese martial arts.

A sword is an edged, bladed weapon intended for manual cutting or thrusting. Its blade, longer than a knife or dagger, is attached to a hilt and can be straight or curved. A thrusting sword tends to have a straighter blade with a pointed tip. A slashing sword is more likely to be curved and to have a sharpened cutting edge on one or both sides of the blade. Many swords are designed for both thrusting and slashing. The precise definition of a sword varies by historical epoch and geographic region.
