The invention of the fish hook changed history. More effective than spears or bare hands, fish hooks allowed humans to fish deeper water and opened the door for so many things, including, many centuries later, thick catalogs of fishing gear. The first hook-type devices, called gorges, were used during the Stone Age. Gorges were small pieces of wood or bone sharpened on both ends, with a line tied to the center. When embedded in bait, the entire gorge could be swallowed by a fish, and when the line jerked tight, the gorge would lodge across the throat of the fish. Later, the traditional fish hook was carved from bone. The invention of metal made for better fish hooks, and after centuries of progress, today’s hooks are sometimes chemically sharpened and surgical in their effectiveness. But the basic shape of the hook remains the same.
