Best Answer: Fingers tend to take a while to heal when cut badly, i would say anything up to 2 weeks to heal properly, and make sure you keep it covered for most of the time, fingers tend to dry out quick so take longer to heal when uncovered, i've cut my fingers heaps of times at work.k so im not going into detail cause it's a long story how the cut happened but it was deep and bloody. the wound is mostly closed but pops open in small places from time to time n bleeds.
