An atlatl (from Nahuatl ahtlatl, pronounced [ˈaʔtɬatɬ]; English: /ˈɑːt.lɑːtəl/[1] or /ɑːtˈlɑːtəl/[2]) or spear-thrower is a tool that uses leverage to achieve greater velocity in dart-throwing, and includes a bearing surface which allows the user to temporarily store energy during the throw. It consists of a shaft with a cup or a spur, which may be integrated into the weapon or made separately and attached, in which the butt of the projectile, properly called a dart, rests. It is held near the end farthest from the cup, and the dart is thrown by the action of the upper arm and wrist. An atlatl can readily achieve ranges of greater than 100 meters and speeds of over 100 km/h.[3]
