Quoting Ben Parker
OOOHHH, that looks really cool. But now when you get a new jedi or sith don't doesn't it look silly with their simple lightsabers and these awesome lightsabers?
I just make them custom 'sabers, too. Right now I have Obi-Wan's, Anakin's, Vader's, Yoda's (not posted), and Ahsoka's; and Ventress and Dooku come with fairly good lightsabers already. So only Mace doesn't have one.
