The Bill Lewis Knock-N-Trap is the younger sibling of the world famous Rat-L-Trap, which is perhaps one of the most famous lures ever made. The Knock-N-Trap features the same great fish catching profile and action but substitutes Rat-L-Trap’s high pitch rattling sound for a low-frequency knock that beats like a drum. Versatility is the Knock-N-Trap’s greatest strength, as it can be fished at just about any depth in a wide variety of cadences. They’re perfect for anything from bass and walleye in your local lakes to stripers and snook in inshore waters.
