When I do wiring repairs, I use my 30 + year old electric soldering iron / pencil. The guys at work tell me the Smithsonian is looking for it, and want theirs back.) It has been dropped and pieced together countless times, but refuses to die. So I keep it and continue to use it to this very day.
Today I heard just about the craziest thing. One of the guys told me that since it is electric, and has current running through it, that it is possible that in the event I would ever be on an airbag circuit, or one multiplexed to the airbag circuit, I could set off said airbag. They were strongly suggesting I ditch my archaic soldering gun, and get a electric torch type soldering kit instead.
Sure thing. I get stuck under a dash with a mini torch, and set the car on fire. That's better than blowing up a airbag, eh?
Ever hear a thing like this?
