Tady went above and beyond in making a new series of assist hooks for bluefin fishing. These prerigged assists use BKK hooks and heavy duty kevlar covering a 49 strand stainless steel cable that prevents any kind of abrasion failure. You'll never have to worry about a bluefin chewing through the cable even if the kevlar gets cut.
These are perfect for the top or bottom side of the jigs but we wouldn't recommend running them on both sides for bluefin since we see a lot more fouled fish that take twice as long to land.
