A grappling hook is a tool used to grab or secure objects, often employed in climbing, rescue operations, or maritime activities. It typically consists of a metal hook attached to a rope or cable. When thrown, the hook can catch onto surfaces like walls or trees, allowing the user to ascend or pull objects toward them. Grappling hooks have been used throughout history, from pirates using them to board ships to modern-day climbers scaling steep cliffs. They are also featured in various video games and movies, showcasing their versatility and adventurous appeal.
