Flambard, flammard, and Flammenschwert
The two-handed flame-bladed sword is called flambard, flammard or by the German Flammenschwert (literally "flame sword"). These swords are very similar to two-handed sword or Zweihänder. The only difference being the blade. Like other zweihänder they were used during the 16th century by the Landsknechts, by well-trained and experienced swordsmen, called Doppelsöldner (double soldier) because they received double pay.
