Make a Simple Wire Stripper With a Clothespin and Pencil Sharpener
If you need to do a little electrical work but don’t have a wire stripper handy, you can make one with a few things in the house.
This MAD Science Hacks YouTube video shows you how to make a wire stripper in about five minutes. Find an old pencil sharpener and remove one of the blades. Then attach the blade to one side of the clothespin (at the end that opens when you press down on the spring). You want the blade to be in place, so when the clothespin is closed, the edge of the blade barely overlaps the small groove in the wood. Once attached, as shown in the video, you can pinch the clothespin at the end of the wire, twist it a few times, and quickly strip the wire.
