KOBUDO (WEAPONS)
Five weapons are mainly used: Sai, Bo, Tuifa (or Tonfa), Nunchaku and Tekko. These weapons, except for the Sai, were originally believed to be farm implements. Since it was illegal (under penalty of death) to carry or use weapons in the 1600’s in Okinawa, weapons had to be made from every day implements.

BO
The bo is a long wooden staff about 6 feet in length. It was perhaps developed from a farming tool called a tenbin: a stick placed across the shoulders with baskets or sacks hanging from either end. The bo was also possibly used as the handle to a rake or a shovel.
SAI
In ancient times, the sai was used by officials to arrest criminals and to hold back crowds. The sai also could be used to defend against the bo, nunchaku, tuifa or sword.
Tuifa or Tonfa
Tuifa or tonfa refers to two pieces of rectangular hard wood, each about 16 inches long, with a grip attached. It is often said that this weapon was used in connection with milling stones.
Nunchaku
The nunchaku is a pair of hard wooden sticks with a cord attached at the end. The centrifugal force produced by swinging the nunchaku makes it an effective weapon. It is often said that nunchaku were used in rice thrashing.
Tekko
Tekko is a hand held weapon similar to brass knuckles. This weapon was originally made from horse shoes.
