last year i was cutting some wood for a work in the university. I was with a piece of foam in my hand, and i was doing a lot of pressure to cut it.....but i didnt realised that one of my fingers was grapping i¡the form in the wrong place.
I did more pressure to cut it and then,,,,with a lot of force i sliced the foam so strongly that the knife hitted the the table where i was sit (my hands were in the air).............but in the way between the knife and the table...........was my finger!!.
Right away i was like "ooooouuucccchhhhh!!!". grapping my finger, i went to the bathroom and then when i cleared the lot of blood that was emerging from the finger...i saw that almost all my nail was cut in a half including some "meat".
I returned to the table, and i found a little piece of my finger in it!. I was so scared, and it was sooooooo painfull.
It took me more or less 6 months to be cured completely.
