I do think Chen called his element energy, if you can trust Chen. He does seem to know his elements.

What is confusing is Kai's dad seems to have unlocked his fire powers without the sword of fire which means it is not necessary for Kai or the others to have had their weapons to unlock their powers. Kai's dad does make large holes in the theory.

They do randomly ditch the elemental blades after the defeat of the dragon overlord, which makes no sense.
