My assistants husband lost half of his left hand. Only his thumb left. It was that or his face. Experienced? Yes, about 40 years in NZ. Forestry, then treesurgery and hedges.
The patients I reconstructed the jaws and faces on in Sweden? Yes, forestry workers since teens. Professionals. Most kick backs were caused by nails and a few by bullets. In most cases the chain was being braked, but still horrific damage.
It can stop the chainsaw by the same principle as the gloves and overalls filled with the weird fibers I believe.
