Roboworm Rebarb Hooks are designed specifically for rigging soft plastic worms. All Roboworm Rebarb Hooks are made with high quality Gamakatsu Hooks. The molded plastic "Rebarb" on the hook shank holds the worm securely in place. When rigged properly, the plastic Rebarb is pushed through the worm and backed up to wedge against the inside of the worm to prevent it from sliding down.  Available in all sizes to fit your favorite Roboworm.
