The “flamberge” is so named for the wavy “flame-like” shape of its blade. It was cited by Bossewell, 1572 [II.132v], who termed it a “sword wavy”.
The Order of the Flamberge, of the Barony of the Flame, bears: A flamberge gules, hilted and the blade enflamed Or.
Max Erich von Baden bears: Per pale gules and sable, two flamberges in saltire Or surmounted by a skull argent.
