Gorge hooks are the oldest fishing hooks, many examples are found in prehistory.
The idea is that fish swallows the baited hook length ways, but when tension is applied the hook stands on end and lodges in the jaw and palate of the fish.
Note one end is longer than the other from the line connection, which helps the hook stand in the gullet of the fish when tension is applied to the line.
We used bamboo hooks and agave fibre double twist fishing line, these are extremely strong. In minutes you make them up and have lines in the water.
Just shove the hook up the length of a grasshopper or moth, and these will float on the surface splashing and flapping around attracting the fish. Very hard for a fish to ignore that, it’s a call to dinner.
