This might surprise some of you for a self defense resource The Outdoor Channel. http://outdoorchannel.com/the-best-defense. I watched many of these found most of it to be very good.
The knife fighting self defense moves make sense. They are intended to stop the attackers ability to maintain his attack. This is accomplished by cutting the ligaments or muscles controlling the arms and legs. Like inside the elbow, the bicep, that big ligament in the front of your armpit and right above the knee cap. Take what is given to you, take the open easy hit.
