Throwing stars, also known as shuriken, are traditional Japanese concealed weapons used by ninja and samurai. They are typically star-shaped and made of metal, designed for throwing at targets. While often associated with martial arts and popular culture, their primary purpose was to distract or injure an opponent rather than to serve as a primary weapon. These weapons come in various shapes and sizes, with the most common being the four-pointed star. Throwing stars require skill and practice to use effectively, as accuracy and technique are essential for successful throws. Today, they are often used in martial arts training and as collectibles.
