You haven't seen Deep Dive? You should download it and watch it. One place (of many) to get it is at kingdomehearts2.net. It's pretty cool, and those keyblades get used quite a bit.

My favorite is the Oathkeeper. I like the way it looks, and for almost the rest of the game it is the best keyblade, for a magic user at least. The Oblivion is stronger, but it has MP-1, which is bad. The Lionheart is stronger also, but you don't get it until almost the end of the game.
