The nunchaku (Chinese: 雙節棍,双截棍, shuāng jié gùn; 兩節棍,两截棍, liǎng jié gùn "Dual Section Staff"; 二節棍,二截棍 gèr jié gùn "Two Section Staff"; Japanese: ヌンチャク listen; 梢子棍, shōshikon "Boatman's staff,"; Korean: 쌍절곤 (ssang jul gon) ; also colloquially called "nunchucks," "chain sticks," "chucks," "nunchukkas,") is a traditional weapon of the Kobudo weapons set and consists of two sticks connected at their ends with a short chain or rope. A sansetsukon is a similar weapon with three sticks attached on chains instead of two.

History

The popular belief is that the nunchaku was originally a short Southeast Asian flail used to thresh rice or soybeans (that is, separate the grain from the husk). It is possible that it was developed in response to the moratorium on edged weaponry under the Satsuma daimyo after invading Okinawa in the 17th century, and that the weapon was most likely conceived and used exclusively for that end, as the configuration of actual flails and bits are unwieldy for use as a weapon. Also, peasant farmers were forbidden conventional weaponry such as arrows or blades so they improvised using only what they had available, farm tools such as the sickle. The modern weapon would be an effective flail.

Some sources say that the first Song Emperor was in battle when an enemy general cut the end off of his staff. Instead of using a different staff, he connected the two pieces with a short section of iron chain, creating a weapon known a "sweeper". At the time, it was not illegal to carry a weapon, but it was inconvenient to carry a sweeper because it was a long stick with a loose section, so some people shortened the staff section so that the weapon could be tucked in a belt. This was called a "small sweeper", later renamed the nunchaku.

Another popular theory is that the nunchaku originated from China in the Song Dynasty. It was named "da pan long gun"(大盤龍棍), meaning great coiled dragon stick. The weapon is composed of one long stick and a short stick connected by horse hair. It was commonly used in wars against cavalry to trap horse legs. The weapon eventually evolved into a short range weapon as seen in our present day nunchaku.

The nunchaku as a weapon has surged in popularity since martial artist Bruce Lee used it in his movies in the 1970s.

Formal styles

The most common martial arts to use nunchaku are the Chinese, Chinese-Okinawan and Okinawan martial arts such as some forms of karate/kobudo, but some Eskrima systems also teach practitioners to use nunchaku. For its part, Taekwondo teaches how to use one and two nunchaku, though in Korean, they are known as Ssahng Jeol Bahngs, or sometimes Ssahng Jeol Bongs. The styles of these three arts are rather different; the traditional Okinawan arts use the sticks primarily to grip and lock, while the Filipino arts use the sticks primarily for striking, while Taekwondo teaches a little bit of both.
