Back in the late 1950’s I had a neon tester that had the screwdriver blade cut short and put the rest into a plastic tube, I think resistors came in the tubes, and it was therefore isolated. Used as a guide to tell if line output transformers were working. Only needed to get it within about 2-3 inches and it glowed without having to touch anything.
