Typically, the blade was around 45 cm (18 inches) long, on the end of a pole 2 m (6 or 7 feet) long, and the blade was affixed in a socket-shaft configuration similar to an axe head, rather than having a tang like a sword or naginata. Occasionally glaive blades were created with a small hook on the reverse side to better catch riders. Such blades are called glaive-guisarmes.
According to the 1599 treatise Paradoxes of Defence by the English gentleman George Silver, the glaive is used in the same general manner as the quarterstaff, half pike, bill, halberd, voulge, or partisan. Silver rates this class of polearms above all other individual hand-to-hand combat weapons.
Other uses of the word 
The word glaive has historically been given to several very different types of weapons.
- The word glaive originated from French. Almost all etymologists derive it from either the Latin (gladius) or Celtic (*cladivos, cf. claymore) word for sword. Nevertheless, all the earliest attestations in both French and English refer to spears. It is attested in this meaning in English roughly from the 14th century to the 16th.
- In modern French, a "glaive" most commonly refers to a gladius, the Roman short sword.
- In the 15th century, it acquired the meaning described above.
- Around the same time it also began being used as a poetic word for sword (this is the main use of the word in Modern French).
- Starting around the 1980s the word began to describe a fourth type of weapon: a whirling projectile blade similar in structure to a shuriken but much larger and cast like a chakram or hunga munga. This fictional weapon is usually portrayed as being able to return to its wielder, much like a boomerang. "Glaives" of this type have shown up in several films (such as Krull, Blade, and Batman Begins) and other aspects of fantasy fiction (e.g. video games such as Warcraft III, Dark Sector, or Warframe).
- OED s.v. Glaive: "Hatz-Darm. regard OF. glaive as an adapted form of L. gladius (through the stages gladie, glaie, glavie). Ascoli supposes it to represent a Celtic *cladivo- (OIr. claideb sword, Gael. claidheamh). Neither view, however, accounts for the earliest meaning of the word in OF., which is also that of MHG. glavîe, glævîn, MDu. glavie, glaye, Sw. glaven."
- OED s.v., section 1, lists examples in this meaning from 1297–1592.
- OED s.v., section 2, lists examples in this meaning from ca. 1450–1678.
- OED s.v., section 3, lists examples in this meaning from ca. 1470–1887.
