Nunchaku & Sansetsukon
Nunchaku. Nunchaku, a farmer's tool converted to a self-defense weapon that in the hands of an expert, could be a formable weapon; but in the hands of an amateur, it could provide considerable entertainment. Nunchaku (also spelled nanchaku or nunchuku) is known to many Westerners as nunchuks or numb-chuks. Did it originate in China (or some other southeast Asian country) and later introduced to Okinawa: or was the weapon indigenous to Okinawa? Possibilities include: (1) Chinese weapon, (2) Okinawa threshing flail, (3) cart rail, or (4) horse bridle.
Even the word nunchaku rings with controversy. The word may be from the Japanese pronunciation of a two sectional staff, or it may be from the word used for horse bit or bridle. By combining two Japanese words: 'nun' meaning ‘twin’ and 'shaku' the approximate ‘length of bamboo between two nodes, one ends up with the word 'nunshaku. The word for Okinawan horse bit or bridle is nunchiyaku, also similar to nunchaku. The parts of old nunchaku consist of two short staffs attached by horse hair.
