Extend your arm to align it with your target, then bend your arm and lift the knife next to your head. Re-stretch your arm to aim at the target and release the knife at an angle of approximately 45 degrees. This will cause the blade to fly in an arc and reach your target without turning. Some of the techniques that don't rotate require the launcher to brush the turn of the knife with a finger.
For this, the shape of the knife is very important. Make sure that the throwing knife has a round and smooth spine, it should not have any bulges that stick out that could prevent you from brushing the knife. Non-turning throwing refers to any technique in which the knife DOES NOT rotate from end to end during its trajectory. The knife is always grabbed by the handle.
Despite the name, some rotations are common, usually 10° to 100°. Other terms for this technique include a quarter turn, direct throw, and spear-shaped launch. Throwing without turning has its roots in traditional Asian martial arts. As the name demonstrates, knives that don't rotate are those that travel in a straight line with the sharp edge facing the target everywhere.
This method is usually applied at short launch distances within a 10-foot radius of the target. However, you can also launch them from farther distances with practice. This is a favorite for throwing spears without turning. It's a little heavier than what is normally used to avoid turning, but that gives it a good weight, so you don't have to put so much force on it so that the knife can fly long distances.
The ability to control and limit knife rotation is the primary skill of instinctive knife throwing. Instinctive: The knife is thrown from any distance, while the launcher controls the rotation of the knife. Another reason to opt for balanced knives is that you can switch from a balanced knife to any other balanced knife. There is a certain type of throwing knife that does not rotate and has been called a “cheating” throwing knife.
However, rotational throwing is more common among experienced knife throwers, since it requires being very thorough when shooting, calculating the distance from the target, the required turn count and the knife's grip point. The balance of the blade is in terms of its weight distribution along the blade and the handle or also known as the center of gravity. The ability to control and limit the rotation of the knife is the main skill of instinctive knife throwing, and most people find that it is best to maintain a balance with the heavy handle. This means that you'll release the knife when the tip points upwards; the knife will naturally rotate during its journey.
THORN This American style of “throwing combat knives” or “throwing street knives” without turning was initiated by Ralph Thorn in the late 1990s. There is a strong correlation between the various knife throwing substyles and typical knife lengths. This knife weighs a bit on the heavier side, which is useful for the knife to reach longer distances. This method uses the handle with the driving finger: the knife is held between the thumb and the curly middle finger, while the index finger rests on the spine of the knife.
