Oh it does hurt - While using my Berettas for coaching I have on a couple of occasions (didn't learn the first time!!) pinched the bit of the palm next to the little finger - didn’t know I knew so many expletives!!
On another occasion a client left his thumb resting on the top leaver - unfortunately for him the chequering had produced a razor sharp serrated edge. It was on this occasion I was able to see the damage human blood can have on the blacking of the barrel!!
