Square Enix is notorious for (leaving things out/the way they) for the sake of it being cool. The idea of Zack continuing the wear and tear tradition is cool and speaks to his character. Zack actually USING the blunt sides wouldn't have been as cool.I think I remember the game telling me he only used the blunt side, which I guess meant the side or maybe the top, but I always saw him use the sharp side on the bottom. Same with Cloud, it makes no sense to me. I want to assume it was just a bad translation job, but how could they mess that up?
