When the hinges are on the inside, it will make it harder for someone to try and pry open the safe and if you manage to buy a safe with a reinforced steel door, you will notice that it is heavier and more resistant to standard break-in tools. We always recommend that buyers look at the hinges of the safe that they intend to purchase. The reason for this is because the hinges could possibly be a weakness on a safe and if the hinges are on the outside of the safe, the safe might be more vulnerable and someone could possibly pry open the safe.
