Sword for Montu Warrior

My work from the "Сoncept artist" online course of XYZ School.
Weapon concept.
I had to come up with a really unusual sword that would be a favorite toy for a villain with an inferiority complex.
This sword has three blades, an energy crystal, and looks like something from the Art Deco era.

My assignment was to concept and design a warrior character with a wounded ego. Mixed sci-fi and Egyptian style.
The brief is a separate picture in the carousel below.
