    It's an antenna & it needs to be a certain length - making it a bit gay just adds enough pizazz (length) and it's the ez thing to do from a designers pov.

    Oh, no, the metal ones do in fact use the metal as an antenna?? Can't really tell (but I would guess not).

    So the pattern of the cut is maybe structural (harder to bend with the plastic inside it bcs it's longer?) or just perhaps a CNC simplification.
