Unfortunately I wasn&#x27;t able to avoid the experience, I hit the screw on a silver trimmer in an end stage while looking at another one. Nasty little burn with dead tissue in the center and living tissue all around it. 35 years later it is <i>still</i> there, I don&#x27;t expect that it will ever properly heal, it&#x27;s a dead bit in the middle of a living finger.
