Nunchaku & Sansetsukon
Nunchaku is a weapon indigenous to Okinawa.
Originally, a farmer's tool, nunchaku was converted to a self-defense 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. It was originally used as (1) Okinawa threshing flail, (2) cart rail, and/or (3) 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 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.
