a staff of wood from 6 to 9 feet (about 2 to 3 m) long, used for attack and defense. It is probably the cudgel or sapling with which many legendary heroes are described as being armed. The quarterstaff attained great popularity in England during the Middle Ages. It was usually made of oak, the ends often being shod with iron, and it was held with both hands, the right hand grasping it one-quarter of the distance from the lower end (hence the name) and the left at about the middle. The staff was used as a foil, or practice substitute, for the long, two-handed sword of the period. In earlier times, it may also have been used as a practice weapon for the spear and pike
