As featured on the Owner Twistlock hooks, these interchangeable stainless steel Centering Pin Springs (CPS - U.S. Patent 7,841,127) attach to hook eyes, and allow any soft plastic bait to be "permanently" secured by inserting the pin in the center of the bait's nose and then screwing the bait onto the coil spring to rig perfect everytime! The CPS has far superior holding power compared with barbed stick-pin holders.
