The term 'Fish-Landing Hook' is a tool used by fishermen to help them land their catch. It is also known as a GAFF, which is a four-letter word. A GAFF is a long pole with a sharp hook at the end, which is used to snag and lift fish out of the water. The hook is usually made of metal or wood and is attached to a rope or line. This tool is used to help fishermen bring their catch onto the boat or shore.
