You also have to remember... this is a Final Fantasy game. Exaggerated weapon size is par for the coarse.

I'm sure they will have a wide variety, though, from dungeon drops, etc. Just look at every other weapon type in the game. They have their comically large weapons, the super gaudy types, and the more realistic types.

You'll just have to find one you like and glamour it. I might even hazard a guess that one type might even come without the guard.
