A flame-bladed sword or wave-bladed sword has a characteristically undulating style of blade. The wave in the blade is often considered to contribute a flame-like quality to the appearance of a sword. The dents on the blade can appear parallel or in a zig-zag manner. The two most common flame-bladed swords are rapiers or Zweihänders. A flame-bladed sword was not exclusive to a certain country or region. The style of blade can be found on swords from modern-day Germany, France, Spain,[1] and Switzerland.[2]
