Fishing hooks, also known as gaffs, are a type of hook used in fishing. They are typically made from metal and have a sharp point at the end, allowing them to penetrate the skin of a fish and hold it in place. Gaffs are often used when fishing for larger species of fish, such as tuna or marlin, as they provide a secure grip on the fish. They can also be used to help land a fish that is too large to be reeled in by hand.
