The Owner Twistlock Flipping Hook features a specially angled line eye and patent-pending CPS (Centering Pin Spring), allowing you to rig your baits quickly and perfectly straight every time. The CPS holding power is also second to none, so you don't have to constantly adjust or replace your bait. Constructed from Owner's new Zo Wire, the Owner Twist Lock Flipping Hook is significantly stronger than traditional high carbon steel wire hooks, and their diameter is also actually smaller, which combined with Owner's new Silky Gray frictionless finish, delivers much quicker penetration.
