The tonfa (Okinawan: トンファー tonfaa, Malay: topang, Chinese:柺; pinyin:guǎi) also known as tong fa or tuifa, is a melee weapon best known for its role in the armed component of Okinawan martial arts. It consists of a stick with a perpendicular handle attached a third of the way down the length of the stick, and is about 15-20 inches long. It was traditionally made from red or white oak and wielded in pairs. The tonfa is believed to have originated in either China or Southeast Asia where it is used in the respective fighting styles. A similar weapon called the Mai sok san is used in Krabi-krabong and tomoi.
