There is also a bonus keyblade you can get that has EXP0, so you get no exp with that keyblade equiped. The difference is you can equip it in all 4 difficulty modes. However, you aren't able to get it till pretty late in the game.

And I did't look at the the post dates... just the person before me. Probably not really worth posting in this topic anymore since its kinda old. My bad.
