Gamakatsu calls the Assist 720 hooks heavy-duty, but thats an understatement with these bruisers! The made in Japan, Gamakatsu Assist 720 Heavy Duty is the ultimate in big game fish rigging and uses an ultra-strong, incredibly sharp Gamakatsu saltwater hook. A four-strand braid of abrasion-resistant polyethylene cord provides a whopping 880-lb combined test strength, while the ring makes it fast and easy to connect the assist hook to the jig eye using a split ring.
