The most popular assassins in the world are undoubtedly the ninjas. They are Japanese martial arts masters who seem to have mystical powers. Their favorite weapon of choice is the throwing star or shuriken. They were known to appear and disappear with a cloud of smoke and can climb walls and walk on water. Their feats are so amazing that a lot of people doubted their existence.

The fact is ninjas do exist even today. Only 3 ninja legitimate families are left. These 3 families can trace their roots all the way back to the 15th century to prove their existence. These 3 families are Iga, Tokugure, and Edo. The throwing star or the shuriken is a throwing weapon. Unlike in movies, these weapons won’t kill you immediately when hit. The weapon’s purpose is to graze you. Since the shuriken is laced with poison, death will soon follow.
