Knife Switch

Knife switch for Halloween

For Halloween I made a knife switch and put it in the laundry room for now. It will eventually go into my shop. The switch is attached to the wall over the light switch and is fully functional. It makes a creepy wooden sound and the kids love it. You can see the calender in the room is set to October. Happy Halloween!!
