Quarterstaff

A quarterstaff (plural quarterstaves), also short staff or simply staff is a traditional pole weapon and a technique of stick fighting.

The term is generally accepted to refer to a shaft of hardwood from 6 to 9 feet (1.8 to 2.7 m) long, sometimes with a metal tip, ferrule, or spike at one or both ends. The term "short staff" compares this to the "long staff" based on the pike with a length in excess of 11 to 12 feet (3.4 to 3.7 m).
