Small throwing knives are more difficult to use than larger ones. They are extremely responsive, and even the tiniest flaw in your throw can send them wildly off course. Because they are lighter, they also give less tactile feedback, making it harder to learn to time your throw by feel. Learn to throw with a larger knife if you can, then progress to a smaller one.
Balance the knife on your index finger and find the point where it balances perfectly. This is called the fulcrum, or center of gravity.
Grab the blade at the fulcrum between your index finger and thumb. The blade should be facing you and the handle facing up.
Take a step forward with the opposite foot to your throwing arm. The distance between your feet should be about twice the length of one of your feet, but it can be longer or shorter if it feels more comfortable.
Raise your elbow until it is facing towards the target. Your hand should be beside your head in a position that feels comfortable. You may want to hold the knife slightly behind or above your head if it feels more natural.
Practice the right movement before throwing the knife. Slowly shift your body forward while straightening your arm out towards the target without snapping your wrist. Try to get as straight a movement as possible.Small knives wobble very easily, so it is important to not turn or twist your arm.
Throw the knife. Go through the movements in step 5 quickly, releasing the knife at the point where your arm is straight up.
If you find the knife is wobbly or unpredictable after you practice for a while, try throwing with your arm only. Hold your shoulder still and do not shift your weight forward. This may allow you to more precisely control a small knife.
