Those are some scary stories indeed. Makes a guy think, and hopefully slow down.
My return to the hobby has been relatively personal injury free, but a quick one to share....
Before my recent and first adventure with PE, had read how sharp the stuff is and was careful. The other day, having finished all the PE work I was going to do, I moved the leftovers and spare frets to their original packaging for spares storage.
Later realized I had a rather nasty paper-cut like cut on my finger. I guess all the warnings are right.
Not very exciting compared to the above tales, and I hope to keep it that way. Hope we all do, in fact.
