The Shaky Head features Owner's TwistLOCK "Centering-Pin-Spring" (CPS - Patent Pending) molded into the lead. Small diameter finesse baits can be "permanently" secured by inserting the pin in the center of the nose of the soft plastic, which can then be twisted (Screwed) onto the TwistLOCK coil spring to rig perfectly every time! Ideal for weedless-style Texas Rig'n, and on the bottom, contoured jig head "rocks" forward to present baits in a tantalizing nose-down position. Round bend, light wire hook has a 45° cross eye, Super Needle Point and a black chrome finish. All weights come with a 4/0 hook and 4 per pack.
