"You broke it? You bought it!"

It's not repairable... maybe the person from whom you "heard that without the key that came on the old schick blades in the metal case u kinda just get a small flathead pry just a little then slide old out with the side of the new razor" will contribute to the purchase of a new one. And get real... these are effing-sharp razor blades, and there's a reason the delivery mechanism is constructed as it is.
