Who are we, to understand the marvelous technology in FVII??
It's suposed to be a secret but the sword is actually made of lego! So he just took it apart and kept the pieces in his backpack. :cloud:
I agree. We should not question the genius that is FFVII!
Going back to the question though, maybe he forgot to cover that part of the sword with vanishing cream? I don't know.
