Information: - A pole weapon or polearm is a close combat weapon in which the main fighting part of the weapon is fitted to the end of a long shaft, typically of wood, thereby extending the user's effective range. Glaives, poleaxes, halberds, and naginata are all varieties of polearms. - An axe (in American English also spelled ax) is an implement that has been used for millennia to shape, split and cut wood; to harvest timber; as a weapon; and as a ceremonial or heraldic symbol. The axe has many forms and specialised uses but generally consists of an axe head with a handle, or "helve". - A halberd (also called halbard, halbert or Swiss voulge) is a two-handed pole weapon that came to prominent use during the 14th and 15th centuries. The word "halberd" may come from the German words "Halm" (staff), and "Barte" (axe). In modern-day German, the weapon is called a "Hellebarde". The halberd consists of an axe blade topped with a spike mounted on a long shaft. It always has a hook or thorn on the back side of the axe blade for grappling mounted combatants. It is very similar to certain forms of the voulge in design and usage. The halberd was usually 1.5 to 1.8 metres (5 to 6 feet) long. - A voulge (occasionally called a pole cleaver) is a type of polearm that existed alongside the similar glaive in medieval Europe. Superficially, a voulge might strongly resemble a glaive, but there are some notable differences in construction. First, 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. A voulge thus looks something like a squashed bardiche, or just a meat cleaver attached to a long pole. - The Lochaber axe is a type of halberd that was used almost exclusively in Scotland .
