Glaive
A polearm with a curved single-edged blade
The glaive is a medieval European bladed polearm: a curved, single-edged blade of 45–60 cm mounted on a wooden shaft 180–210 cm long. Specialized for cutting rather than thrusting, the curved blade delivers deep slashing wounds, and many variants feature a hook on the spine to pull mounted warriors from their horses. The weapon was particularly effective for infantry facing cavalry or defending narrow chokepoints such as gates and bridges, and was widely used across 14th–16th-century Europe — most prominently in France, Italy, and Switzerland.
Origin
The glaive appears in European arsenals around the 14th century and remains in service until firearms dominate the battlefield in the 16th. Its name descends from French glaive ("sword"), itself from Latin gladius. Curved polearms of the same family arose independently across nearly every civilization — the Japanese naginata, the Chinese guandao (Guan Yu's Green Dragon Crescent Blade), the Korean woldo, and the Russian sovnya all share the lineage. In Europe the weapon is generally thought to have evolved from agricultural tools such as the scythe and bill.

Stories
Infantry swung the glaive in wide arcs to cut down horses or knights at the moment cavalry tried to break their line. It was equally prized for holding narrow chokepoints — gates, bridges, staircases — where pikes could not be brought to bear. English foot soldiers carried glaives throughout the Hundred Years' War, and the burgher militias of late-medieval Switzerland repeatedly cut down armored knights at Sempach (1386) and Arbedo (1422) using glaives and halberds. The curvature of the blade made it especially well suited for finding gaps in plate armor.
Weakness
Poorly suited to thrusting and outranged by the pike (4–5 m) in close formation, the glaive also demanded considerable swinging room and was awkward in tight ranks where soldiers stood shoulder to shoulder. With the spread of the matchlock in the 16th century, mounted shock cavalry declined rapidly and so did the glaive's reason for being.
Cultural Significance
The glaive became emblematic of late-medieval civic militias and professional soldiers, and is most closely associated with the Swiss Reisläufer mercenaries who carried it alongside the halberd. Modern ceremonial weapons of the Vatican's Swiss Guard still echo the form. The word glaive itself, meanwhile, drifted in later English into a poetic synonym for "sword," appearing from Shakespeare through Tolkien as a literary flourish for a flashing blade.
In Popular Culture
Standard equipment in tabletop RPGs from Dungeons & Dragons to Pathfinder, and a regular fixture among Warhammer and other miniature ranges. The 1983 sci-fi film Krull repurposed the name for its five-bladed boomerang-style weapon, and this image — a thrown, multi-bladed disc — has since been imported into many video games and fantasy works. Insect Glaive in Monster Hunter and various "glaive"-class weapons in Skyrim and Diablo II continue that lineage.
Trivia
- The throwing "glaive" most modern fantasy media depicts owes its shape entirely to the 1983 film Krull, and bears no resemblance to the historical pole weapon.
- Repeated Swiss infantry victories over Habsburg knights at Morgarten (1315) and Sempach (1386), won partly with glaives and halberds, marked the beginning of the end of the European age of the armored knight.
- The Korean martial arts manual Muyedobotongji catalogues a closely related curved polearm called the woldo ("moon blade") as its own discipline, and proficiency with it was part of the Joseon military examinations.
