The Jackall Knockin’ Jaw is characterized by it’s protruding lower jaw that allows the bait to move along the bottom laterally with its jaw knocking against anything it comes in contact with to create an enticing vibration. With three places to tie your line you can work the bait on a fast retrieve, a slowretrieve, or a lift and fallretrieve. The lower jaw also makes this a great vibrating bait for when the fish get spooked from thetraditional sound of a lot of rattles.
