⚡ This saw stops in 5 milli-seconds to save woodworkers from cutting off their fingers
Everybody knows one of these old woodworkers who are missing one or two fingers because they cut them off accidentally.
This saw blade has a small electrical current going through it.
As soon as a human touches the blade the signal changes, because the human body is conductive of electricity.
That makes the blade stop immediately.
Any other inventions that are potentially life saving that you can share?
