A jighead with the hardware cut off, or a jighead poured with no hardware (unless the keeper is a wire and not a lead collar) will act as a Worm Nose Weight for a Neko Rig.
Edit...laying here trying to fall asleep, fretting about this job I'm on...I think that a small lead weight stuck into the nose of a plastic worm, only held in by the keeper/collar of the lead part, with a fish shaking its head, the Neko Rig might ought to be renamed to the Eye Remover Rig.
