A voulge (also spelled vouge,[1] sometimes called a couteau de breche) is a type of polearm that existed in medieval Europe, primarily in 15th century France.
[2] A voulge would usually have a narrow single-edged blade mounted with a socket on a shaft.
The weapon could additionally feature shaft reinforcements called langets and rondel protection for the hands at the base of the blade.
There is a popular erroneous definition of the word voulge in modern times, which refers to a pointy cleaver-like weapon blade attached to the shaft with two hoops like a bardiche.
This definition is incorrect and started in the 19th century with Viollet le Duc, and the weapon in question is an early form of halberd.
