Haven't cut my fingers or any other part of me but my little grandson picked up the cutter, i gently took it away, and a few seconds later looked at him and he had blood all over his face, hair, etc. One deep cut on a finger. Was able to get some steri-strips on it and a pressure bandage. That was his first band aid and he showed it off with pride. the cut healed and I learned a big lesson. My cutters are all closed and when the little ones come over they are up high and out of sight.
