Abstract: A projectile is provided, including an arrowhead body formed of a predetermined length and coupled to a tip of an arrow shaft, and at least two blades protruding at equal intervals from an outer circumferential surface of the arrowhead body, and shaped to be curved to a predetermined direction to result in a rotation by air during a flight of an arrow, in which one or more ogives for reducing air resistance are formed on outer ends of the blades. Accordingly, the projectile is provided, which can significantly reduce the air resistance during flight compared to the related arrowheads, and since rotation can be induced in itself by the air encountered during the flight, the rotational force and the straightness of the projectile are greatly enhanced, and as a result, it is possible to improve the accuracy of hitting on targets, and increase the destructive power against the target when hitting the target.
