OVERHAND TECHNIQUE: Grip your knife by the blade, with the knife's spine (the square edge) against your hand . The best way to explain this grip is to hold the knife tip like you'd hold a pencil. Then, hold the knife up, with the knife handle up by your ear. Take aim at your target, and bring your arm down as if you were swinging a hammer to drive a nail. The timing of the knife release is critical, and after a few minutes, you'll start to get the hang of it. Pay close attention to the distance from your target, and get a feel for throwing at different distances (5 yards, 8 yards, 10 yards, etc.). It's also very useful to learn to throw the knife both by the handle and the blade.
