P. T. Selbit's Box and Saw

Origins
P. T. Selbit was a magician credited with being the first to perform the illusion of sawing a woman in half. Among fellow magicians, he was known for his inventiveness and entrepreneurial instinct and is credited with creating many successful illusions.

In Selbit's version, a female assistant got into a wooden box that was coffin sized. She would be tied down at her wrists, ankles and neck and the box would be closed. Afterwards, Selbit would saw through the middle of it with a large handsaw. The impression given to the audience was that, because of the restraints and limited room in the box, the assistant's waist must have been in the path of the saw and she would surely have been cut through. Finally the box was opened and the assistant, still with ropes attached, was revealed as unharmed.

Effects
When someone steps gets inside of it, another person must saw the box in half to activate it. When revealed, it shows the person inside has cleanly been cut in half, with no organ damage or pain, and skin forms on top of the cut to protect the internal organs from the elements. When the box is put back together, the person’s two halves meld together. The box and person are both whole again, and neither shows signs of damage or scars. It is unknown whether the person can control their lower half when separated, given how few times the artifact has been used before the Warehouse bagged it.
