Just to note that users of the Scottish NHS don't get the same multiple heatings and gentle handling.
My experience is you get put in an
arm lock by a 100kg ginger nurse who obviously de horns cows in her spare time away from A&E.
The paper clip is then heated to white hot using a blue flame fag lighter.
the paper clip is then placed on the nail and goes through like a hot knife through butter.
Zero pain involved unless the nurse stands on your toe.
