Sharon Friedman – Vigilance and Tranquility

Take a knife and have a partner come at you. to keep yourself from harm simply place the blade between both of you without giving any protection to the air (away from you) and play with the position of the blade. For example you can place the blade in the middle of your chest pointing down with the back of the blade (if it is not two sided) rests on you and when someone comes to pick you up from behind you simply arch your chest forward and free yourself.
