Yubi-bo
From Infogalactic: the planetary knowledge core
Lua error in package.lua at line 80: module 'strict' not found. The yubi-bo was a variation of the larger bo and han-bo. It was only about 8 inches long, and was similar to the yawara. It was first used by the ninja of feudal Japan due to its ability to be easily concealed, yet lethal.
