We had a scissors related accident a couple of weeks ago. Child was using them appropriately, sitting, cutting a piece of paper and cut into her finger, lopped a tiny bit off. Nasty, lots of blood. Dad was very unhappy about the level of supervision, believed that with scissors there should be an adult sitting with the children. I showed him our scissors risk assessment to show him that we really were thinking about safe use. I then showed him how this particular accident was just that - an accident. It was a finger on the child's left hand, the finger was underneath the paper and so its position was not visible to the child. I explained that closer supervision would not have prevented it, the same as not being able to stop children having nasty falls or bumps. And then I assured him that we would be going over correct and safe use of scissors again with all of the children. In spite of still being very unhappy that it had happened, he could see that there wasn't really anything else we could have done to stop it happening. Children have to learn how to use scissors and they do. This child will probably be the most careful of all of them!! Having a risk assessment to hand helped me to handle the situation with an upset parent and although the new EYFS suggests we don't need them all written down, it might prove a useful tool for your situation.
