Green Shad Jack Hammer Chatterbait. The ChatterBait Jack Hammer is among the most refined and highly anticipated baits to ever hit the U.S. market. Its flat-bottom, low center of gravity head and super thin, strong stainless steel blade enable the Jack Hammer to start vibrating quickly and hunt in an erratic, side-to-side motion, just like a frantic baitfish. Its signature head and blade combo allow it to deflect off cover very easily as well, and also allows it to skip easily beneath docks and overhanging trees like no bladed jig before..
