An avulsion laceration of the left index finger. This is a common injury when a pinching motion has occured between two objects. Unless one can get to medical help with a salvaged piece of skin in less than 12 hours, a skin graft as the one aboved should not be attempted. This wound should be thoroughly irrigated, cleaned, and bandaged.
That shit happened to me, my finger was pinched between two glass shard when I tried to open a bottle that broke...
It both pinched and cut my finger
Now I have a pretty bad scar and can't move the finger in some ways
