Flamberge

From Karate, Kungfu, Wrestling, Mixed Fighting Information Source

The Flamberge is an unusual wave-bladed rapier popular with European officers and upper classes during the 1600s. It was considered to look both fashionable and intimidating as well as erroneously believed to inflict a more deadly wound. When parrying with the flamberge, the opponent's sword was slowed slightly as it passed along the length. It also created a disconcerting vibration in the other blade. The term flamberge was also used later on to describe a dish-hilted rapier with a normal straight blade. Certain wave or flame-bladed two-handed swords have also come to be known by collectors as "flamberges", although this is inaccurate. Such swords are more appropriately known as "flammards" or "flambards."
