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.
