The term 'Robin Hood Weapon' refers to two items used by the legendary outlaw Robin Hood. The first is an ARROW, which is a projectile weapon consisting of a shaft with a pointed head that is shot from a bow. The second is a longbow, which is a type of bow that is typically made from a single piece of wood and is much longer than other bows. Both the ARROW and the longbow were used by Robin Hood in his adventures.
