You will need:
* A kitchen knife or utility knife
* Needlenose pliers
* Regular pliers
* A small Phillips head screwdriver
Step 1: Remove the handle
A pair of wires runs up the inside of the handle to the switch. If you want to recover all the wiring in one piece, remove the screws from the handgrip (don't forget the angled one at the back) and pry up the lighter-colored pushbutton; the handgrip will come apart and you can slide the entire aluminum handle off over the 10A SPST switch inside. You can also just cut the wires.
