HOW STURDY SAFES ARE BUILT:
A non-commercial safe body made of 10 gauge cannot stand up to an attack by fire axe, nor can a 12 gauge body safe. It can't be any axe, it MUST be a FIRE AXE with a pike because that is what starts the pierced holes, and then you use the blade to connect the dots to create a hole large enough to get into. Using inadequate gauge steel saves on manufacturing costs, but with those savings, come a steep price. See More Gun Safes Attacked
This makes the safe door removable, which makes it lighter to move or ship. Unlike hidden hinges, exposed hinges allows the safe door to be accidentally slammed open, without damaging the hinges, as well as, being able to open a full 180 deg. The only advantage to hidden hinges is the cosmetics of it. Exposed hinges do not compromise security.
