@Carlos ********
There are like 4 stupid answers on the internet - as I am into martial arts, some of them overlap:
- no one attacks like that, that is absurd stupid
- never happend to me, that is your stupid story
- does not work in the street, just as if gravity and human body mechanics is different "in the street" versus "a Dojo"
- he is holding the knife wrong ... up to you to discuss with your opponent, if he is holding the knife wrong, or to discuss with your immigration officer of the day, if you need a proof of onward travel ...
I am not really sure, but at the moment #1 stupid answer for me is: "never happened to me".
