Re: Screwdriver? Try a spanner!
Have not done that. Close, but have never done it.
Best I have done is to melt the blade of a screwdriver.
Before working on a mains circuit (which I believe to have been shut off), I first meter it, then short it with a screwdriver, just to be sure (taking the appropriate safety precautions, of course - safety glasses, etc)
I have drawn a spark more than once.
