It is a single hook exclusively for jigging that pursues a shape that has good hooking and does not come off no matter where it is hooked on the fish body. The hooking rate is increased by adopting a back shifted wide eye and a gentle twist to the hook point, and the massive wire & round wide gape succeeds in drastically reducing the looseness. In the strength test, it easily exceeded 3/0/70kg, 6/0/100kg, and 8/0/150kg. A single hook that can easily handle not only blue fish such as amberjack and yellowtail, but also baramtu, large amberjack, and tuna.
