Does it matter? At all? Even in some bizarre alternate dimension where there are such things as Sith and lightsabers?
I mean, pedantry where the subject might actually have some bearing on the imaginary universe, fine, that's your fanboy bag, but honestly, even the Star Wars characters wouldn't give a **** what you call your phallic energy weapon of overhypedness.
And the saber itself? Um, take the ring bits off of the end and I could swear I saw that exact thing in a porn movie, but there's nothing outright wrong with it. Mostly because there's not much there at all- it's an untextured tapered cylinder with a few thingies on it. Not even that many thingies. It could honestly be anything, and nobody'd really be able to argue that.
