Jian

The jian (Mandarin Chinese: jian4, , English approximation: dʒjɛn ) 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 in length. The weight of an average sword of 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. Professional jian practitioners are referred to as jianke ( or "swordsmen"; a term dating from the Han dynasty). 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). These swords are also sometimes referred to as taijijian or "tai chi swords", reflecting their current use as training weapons for taijiquan practitioners, though there were no historical jian types created specifically for taijiquan. A guard or hilt protects the hand from an opposing blade. Guard shapes varied, but often had short wings or lobes pointing either forward or backward, the latter sometimes having an "ace of spades" appearance. Early jian often had very small, simple guards. From the Song and Ming periods onward guards could feature zoomorphic shapes, or have crossbars and quillons. A minority of jian featured the disc-shaped guards associated with dao. The jian's hilt can accommodate the grip of both hands or one hand plus two or three fingers of the other hand. Two-handed jiàn of up to in length, known as shuangshou jian, existed but were not as common as the one-handed version. The longer two-handed handle could be used as a lever to lock the opponent's arm if necessary. Grips are usually of fluted wood or covered in rayskin, with a minority being wrapped with cord.
