Noble Flamme

The Noble Flamme is one of the three gifts that were given by the Emperor to Alice's grandfather for his noteworthy service during war. It is a wave-bladed sword. Alice uses the Noble Flamme in the duel against the Rodelian guard during the ball.

Description
[Source: Wikipedia]

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. It is sometimes termed flamberge, meaning "flame blade".

Technique
While largely decorative, some attributes of the waved blade were useful in combat. Parrying with such a sword may transmit unpleasant vibrations into the attacker's blade. These vibrations caused the blades to slow contact with each other because each wave provided additional friction. The unusual cross section of the blade would inflict wider wounds with a thrust while still keeping the blade light.
