I haven't personally......knock on wood, but was at a class just yesterday where our instructor did just that and she bled so badly she had to go get stitches in her hand and we had to reschedule the class. Another gal said this same instructor dropped the rotary cutter on her foot while teaching another class a while ago. Glad to hear yours wasn't so bad that you needed stitches. Really have to have a healthy respect for rotary cutters.
