This clever DIY wire stripper turns the razor blades into a circuit–the moment you slice through the protective sheath of the wire you’re cutting you get a visual indicator that the wire is ready to be rotated.
It’s a rather ingenious design; assuming you cut slowly you’ll never risk over cutting and damaging the inner portion of the wire. The moment the blades touch the wire the circuit is complete and the light turns on.
