Grappling hook

Common card · No. 352792

A grappling hook, or grapnel, is a drag-looking device intended for grappling onto something. It typically has multiple hooks (known as claws or flukes) attached to a rope or cable; it is thrown, dropped, sunk, projected, or fastened directly by hand to where at least one hook may catch and hold on to objects. Generally, grappling hooks are used to temporarily secure one end of a rope. They may also be used to dredge for submerged objects. The device was invented by the Romans in approximately 260 BC. The grappling hook was originally used in Naval warfare to catch ships rigging so that it could be boarded.
