There was a guy who sheared off the tips of his index, middle and ring finger in a sheet metal shear in my metal shop class in high school, I remember him holding his hand up and watching the the blood squirt into the air like one of those fountains you see in a park
The teacher elected me to collect up the finger tip bits in a tissue and go with him to the nurses office, he went to the hospital but they couldn't re-attach the the finger tips either so his three fingers were all the same length after that and he never came back to the metal shop class
I'd see him around school but he said he was okay and didn't care to talk about it much
