On Lucky, she has a sword, however, she doesn't use it nor does she know how to. The sword belongs to Axel. The chakrams are Lucky's main long range weapon which Serenity creates for her later on in the story along with everyone else's weapons. The metal used for the blades are dragon fangs while the rest are Orhiculum metal.

I did create the chakrams in Blender but not the sword, I colored the sword for a placeholder.
