A man named Seth, a murderer who was initially sentenced for life, was released from prison merely five years afterwards on the grounds of an undisclosed technicality. Believing Seth didn't learn the impact of his crime, Jigsaw placed him into a trap. He awoke chained to a table, with two vices on either side. Above him, was a large bladed pendulum that began to swing after the tape was completed. He had to destroy his hands with the vices in order to stop the Pendulum, as his hands were the tools that caused harm to others. In sixty seconds, the pendulum would cut him in half if he would not use the vices. Seth inserted his hands into the vices but pulls the out from not being able to bear the pain. Trying again, he crushes his hands and the Pendulum ceases for a few moments. Seth realizes that the collar around his neck was locked, and that there was no key to open it. After a short pause, the Pendulum descends further and begin cutting his abdomen, eventually slicing him in half, making the trap inescapable. (less info)
