The bo, or stick is probably one of the first weapons that
mankind used to defend or hunt. It could easily be found, was not to difficult to handle,
and could be used for multiple purposes. In Okinawa, the bo probably originated
from a farmtool called tenbin. It is a stick held across the shoulders, on
which fish or waterbuckets could be hung. It could also be originated from
walking sticks monks used to ease hiking and eventually defend themselves.
The techniques executed with the bo, were probably developed very early in
history, and were probably refined after the Heian Era (around 1127 AD).
