Anyone can offend a poet, but no one can pull a knife out of his back.

It is not possible, before the arrival of doctors, to pull out foreign objects from a person, because bleeding can begin, which without professional training can not stop.
If the knife is in the wound, do not remove it. Fix with a thick bandage or patch so that it does not move, and immediately seek medical help.
