Too much of a good thing doesn't exist. The Bill Lewis Knockin'Hammer Trap is an addition to the popular Hammer Trap line. The big difference is that the Knockin'Hammer Trap features a loud knocking sound rather than the traditional Tri-Tone noise that Bill Lewis lures are known for. This knocking sound is known by "trap" anglers to often be the difference in a good day trappin'or a great day trappin'. Available in both 3/8 and 5/8 sizes, the Knockin'Hammer Trap comes in 12 classic Bill Lewis colors.
