Ouch. I think that is the best way to some it up. I was doing some warranty work on some tracking units today and I managed to hit my knucles on my left hand with my soldering iron. I now have a very light surface burn about 5mm by 15mm. It is painful to touch, but most of the time it is fine. That will teach me – although I am not sure what it will teach me. I tended to burn fingers on soldering irons when I was much younger so it is unusual for me to burn myself.
