Looks like Edge of the Irrevocable can come in different sizes and nobody talked so far about it?

Colour me surprised that I don't have to say my goodbye to my Inferno Pistol after becoming a champion of chaos. Did I miss something or could this be for real my 5 seconds internet fame for discovering some gaming knowledge?
Any theories what could be the deciding factor for the size of the sword? Also, minimize the jokes: Yes, I trust in my technique.
