Mighty Magiswords (http://www.cartoonnetwork.com/video/magiswords/). If you don't want to follow the video link, it's a series of shorts about a brother and sister team of adventurers, the Warriors for Hire (Warrior is their family name). They deal with various problems they're hired to solve mostly by use of their many, many magiswords, all of which are highly (if not ridiculously) specialized and capable of shrinking to the size of a swizzle stick. Almost none of them are useable as, well, swords. As you may have gathered, it's a less than serious show.
FATE?
A good start for these threads is for the OP to inform us of his or her extant gaming preferences and restrictions.
But off the top of my head, any superhero game featuring variable power pools/devices will do the trick.
A superhero RPG would be one. Like TSR's MSH.
D&D would be another. The PCs are effectively Wizards with how their arsenal works.
Gurps or BESM could probably handle it too.

Yes, TOON. Or maybe a modified InSpectres (Player says what the sword is supposed to do, then rolls. Good roll means the sword works as described, bad roll means the GM describes what the sword really does.)
