FROM: http://en.wikipedia.org/wiki/Bo weapon
A bo is a long stick usually made out of wood or bamboo, but sometimes it is made of metal or plated in metal for some extra strength. A full-size bo is also sometimes called rokushakubo (六尺棒). This name derives from the Japanese words roku (meaning “six”), shaku (a Japanese measurement equivalent to 30.3 centimeters, or just under 1 foot) and bo (kanji, Chinese character meaning “staff”). Thus, rokushakubo refers to a staff about 6 shaku (181.8 cm, about 6 ft.) long. Other types of bo range from heavy to light, from rigid to highly flexible, and from simply a piece of wood picked up off the side of the road to ornately decorated works of art.

The Teenage Mutant Ninja Turtles (TMNT or Ninja Turtles) are a fictional team of four anthropomorphic turtles who were trained by their sensei, Master Splinter (an anthropomorphic mutant rat) to become powerful ninjas. The story begins when they are sixteen; from their home in the sewers of Manhattan, they battle petty criminals, evil megalomaniacs, and alien invaders, all while remaining isolated from society at large.
