Circle hooks are designed to be used with circle, round or oval shaped baits. The circle hook will rotate in the fish’s mouth until it is securely hooked.

A “Circle Hook” has a shape of a circle and may be used as a bait for fishing for larger predators such as bass and walleye

Some fishermen prefer them because they release from the mouth more easily than ordinary J-hooks that are shaped like Js or have two points at their ends.

Since man first learned how to take fish from the water, the circle hook has been around. From the bone beginnings of anglers in the Pacific Northwest to modern, high tensile models available for the inshore angler, the circle hook has certainly had a serious effect on the hook and saltwater fishing market.
There are some as far south as Key West, Fla., using circle hooks for everything from bridling for big offshore to bottom fishing on the flats for the occasional shark.
