Swung by a number of heroes of chansons de geste and romances, the name became a generic name for a large sword.
[1] In earlier texts, the name is usually given as "floberge" or "froberge" (Italian: Fusberta or Frusberta), but the name developed under the influence of the word "flamber".
[3][4] Flamberge ("flaming"), from the French "flamber", is a term with many connotations, including swords without the flamed-blade.
Egerton Castle used the term to refer to swords that were a transition from the rapier to the smallsword.
Castle makes note of this being the case of certain Swiss rapiers, but flamberge quickly became a disdainful term in France to refer to flamboyant swords.This comes from the French expression "Mettre flamberge au vent", meaning "To put [the sword] in the wind".
