Chris, my answer was a generalised one to a very generalised question, well not even a question. The OP was expecting flash bang wallop techniques to do such as kicking the knife out of the attackers hand with a roundhouse kick, very easily done of course....in films. The basic premise of my answer was that you should not be fighting if you can at all help it, each situation is different. The OP didn't want anything sensible, I could have said ride away on a tiger and he'd have been happy with that though. The 'run away' point was just a point about not fighting is possible. I considered it useless to elaborate without something from the OP that would give us a clue on a situation we could actually comment on. Other's have presumably more patience than I
