I've done it twice already. Vigorously handsawing through deadwood and was apparently not concentrating on how far through the cut I was. Finally I broke through and I jammed the Fanno's teeth right into my knee. Thought nothing of it until my jeans turned red. Then, last weekend, I was using the Fanno to swat twigs down and I happened to be holding the host branch of one of the twigs. One tooth of the Fanno put a hole in my finger nail. On neither of these was I raking the saw across my body...just kind of hammered the teeth into me. Only minor injuries but definitely be careful with the handsaws.
