Knife to knife pressure training plus bonus clip on response from restroom knife assault situation. 

Not realistic? See it all the time, people making comments, as if they have the answer, to a knife attack. The answer is run, if we can't run, then we can only train as they do, to try and minimize the damage. Stop looking so stupid people, by making comments like these. People train to increase their chances. They are not telling you, this is what is going to work, 100% of the time. If you are bored and just like to criticize, make a video, so we can say your amazing ability to deflect a knife attack, 100% of the time. Grow up.
