Throwing knives are knives that are specially designed and weighted so that they can be thrown effectively. They are a distinct category from ordinary knives.
Throwing knives are commonly made of a single piece of steel or other material, without handles, unlike other types of knives. The knife has two sections, the 'blade' which is the sharpened half of the knife and the 'grip' which is not sharpened. The purpose of the grip is to allow the knife to be safely handled by the user and also to balance the weight of the blade.
Throwing knives are used by many cultures around the world, and as such different tactics for throwing them have been developed, as have different shapes and forms of throwing knife. A wielder must be well versed in the various properties of his or her specific knives, such as their center of gravity and the spin of the weapon as it flies.
