Other than a gun, the knife is the most common weapon used in crime. Yet attacks are not just with knives, but with a wide variety of edged weapons: screw driver, syringe, broken bottle, a shard of glass, a shank in a custody environment, and anything else that can cut or stab. Knowing how to survive these gruesome tools is vital. In the world of knife fighting there are only ten angles in which to stab a human being, and only ten angles to cut someone. We call them the Jim Wagner Primary Knife Strike Directions. This series is part of my Assassination Survival Courses.
