Heavy Cover Worm Hook with Tin Keeper has been built to the highest standards to fight the biggest fish in the heaviest cover. The Heavy Cover Worm features our rock solid welded eye, perfect for tying a Snell knot with braid. Gamakatsu has worked with our top pros to design an improved keeper. Instead of a bulky heat shrink barb, the Heavy Cover Worm features a small tin keeper. The keeper has a small compact profile and is strategically placed for superior holding power.
