The trap was a mechanical contraption that was attached to its victims' head and secured with a padlock. A timer was attached to the back of it. Usually, the victim had 60 seconds to find the key, unlock the trap and remove it. If the victim failed to do so the trap would burst open and rip their jaws apart, as the frontal part of the trap was hooked into the upper and the lower jaw. (Saw) The Reverse Beartrap 2.0 was a technically advanced version of the original trap. Like the first one, it was secured by a padlock and had a timer attached to it. There were two different versions of the trap in the theatrical version and the Director's Cut: in the first version, the timer was started once a metal pin was pulled out of the trap, whereas in the Director's Cut, the timer was activated by a lever, which was also connected to another trap.
