Z-Man ChatterBait Jack Hammer Lures are designed by Elite Series pro Brett Hite in collaboration with Japanese luremaker Evergreen International. The flat-bottom, low center of gravity head and super thin, strong stainless steel blade enables these lures to start vibrating quickly and hunt in an erratic, side-to-side motion, just like a frantic baitfish. This lure's signature head and blade combo allows for deflection off cover easily and allows it to skip easily beneath docks and overhanging trees like no other bladed jig.
