The Impalement Wheel is a trap from the Saw franchise, appearing in Saw 3D.

Design and Function

This trap was the third one in a series of tests. The victim of this trap was strapped to a plate, which was in the center of a large metal wheel, by several leather restraints in a horizontal position. To prevent the victim from moving their head away, it was held in place by a metal ring screwed onto the plate. Before the wheel was a contraption with three pointy metal rods. Once the game began, the wheel started to turn forward. Thereby, the victim was slowly moved into an upright position by a pulley system. Eventually, this would cause the three metal rods to pierce the victim's eyes and mouth, killing the person in the process. To survive, the test subject had to rely on the help of a second person. This person had to step into another machine across from the wheel and had to lift two metal bars, to which a heavy weight was attached, to the highest point in order to close a circuit. However, in doing so, four metal spikes pierced the subject's obliques, two on each side of their body. To save the victim in the wheel, the weight had to be held up for the duration of at least 30 seconds. (Saw 3D)


Bobby Dagen's Test

Hello, Bobby. The feeling running through your body is fear: the fear of not knowing if you have what it takes to survive. Before you is your lawyer, who swore the Code of Ethics, but chose to see no evil, in order to benefit herself. Once her device begins to rotate, it will pierce her eyes and mouth if you don't delay its movement for at least 30 seconds. To do this, you must step into the other machine and lift the bars to the highest position, long enough to close the circuit, slowing down her device. If you do nothing, she will wind to her death before the clock runs out. Do you have what it takes to help her? Make your choice.

One of the persons tested in this trap was Bobby Dagen, a man who had gained wealth and fame by publishing his book "S.U.R.V.I.V.E. - My Story of Overcoming Jigsaw", in which he told his readers how he supposedly survived a deadly trap set up by the Jigsaw Killer and how his life developed afterwards. In fact however, he had never been tested by the killer and his whole story was nothing but a lie. The other subject was Suzanne, Bobby's lawyer, who supported his lie for the sake of gaining wealth, even though she knew that his story was merely fabricated. One day, both of them were abducted by Detective Mark Hoffman, the successor of the late John Kramer, better known as the Jigsaw Killer. After subduing them, he took them to the abandoned Clear Dawn Psychiatric Hospital, where he placed Suzanne in the trap. Furthermore, he had prepared a deadly game for Bobby.


Bobby tries to free Suzanne

As Bobby made his way through the building, he eventually reached a door with the words "Verify your self-worth through commitment" written on it. When he entered the room, he immediately heard a woman crying. Thinking it was Joyce, his abducted wife, he yelled for her, but soon realized it was Suzanne, when the light went on. Suzanne had been strapped to trapped in the wheel. Bobby asked her if Cale, his manager and best friend, was trapped somewhere as well. However, she only further panicked and yelled at Bobby to free her. However, as he tried to remove her straps, a large cylindrical cage, similar to the one he woke up in, burst through a window. Inside the cage was a mechanical ventriloquist puppet, which provided the instructions for the next game. In order to save Suzanne, Bobby had to step into the second machine and lift the heavy weight in order to close the circuit for the time of 30 seconds.

Bobby lifts the bars

After Bobby had received his instructions, the wheel started to turn. Therefore, he quickly stepped into the machine and lifted the two bars to which the weight was attached to the highest point. However, in doing so, four spikes pierced his obliques, two on each side of his body. Bobby tried to endure the pain, but eventually let go off the bars. He repeatedly tried to lift the weight up again and was thereby able to close the circuit for a few more seconds. However, just before the game ended, he found himself unable to hold on even longer and dropped the bars. Therefore, Suzanne was killed by the rods with only a few seconds left on the timer. After witnessing her death, Bobby left the machine and hesitantly approached her, looking at her body in horror and disbelief. However, as his game wasn't over yet, he went on to look for his next test. (Saw 3D)


Suzanne's corpse

Suzanne's corpse

Within the next hour, the hospital was found by the Metropolitan Police Department. While a SWAT team made its way through the building in an attempt to find Bobby and end his game, they came across the corpse of Suzanne, who was still in her trap. Seconds later, the SWAT leader heard the agonized screams of Bobby in the distance. Therefore, the SWAT continued its way and left Suzanne behind. (Saw 3D)


  • This trap's alternative name, "See no Evil", is a reference to the Three Wise Monkeys from the Japanese myth. Thereby, it directly refers to Mizaru, the money covering his eyes.
