A voulge (rarely called a pole cleaver) is a type of polearm that existed along side the similar glaive in medieval Europe. Superficially a voulge might strongly resemble a glaive but there are some notable differences in construction. Firstly the attachment of the voulge blade to the shaft was usually done by binding the lower two thirds of the blade to the side of the pole; the glaive would often have a socket built into the blade itself and was mounted on top of the pole. In addition, while both had curved blades that of the voulge was broad and meant for hacking while that of the glaive was narrow and meant more for cutting. Indeed a voulge looks something like a squashed bardiche head or just a meat cleaver attached to a long pole.

In early designs it consisted solely of a cutting edge, but in time voulges often had a 'pointed-top' blade for stabbing. Also hooks were incorporated into the back side of the blade and thus became called "voulge-guisarme".
