I almost lost the fingers on one hand once. I was being lowered down a couple of storeys by a forklift, standing on the forks. Foolishly, I had one hand grabbing the steel frame behind me which moves the forks. As I let go to jump off I felt something lightly brush my fingertips. It was another section of the frame sliding past where my hand had been. If I hadn't let go when I did, my fingers would have been sliced clean off just below the knuckles.
(I might have been going, up. Can't quite remember - it was over 20 years ago. The forklift was an an all-terrain type called a "Sambron" iirc.)
