I'm talking about the stiff wire loop you put a line through then pull it back through a line eye. I know they are cheap, around $3, but I've had to buy a bunch of the little buggers, and they never were where they needed to be when ready to thread a line through a reel line guide or poking line through a hook. I use velcro to attach one to the bottom of each pedestal seat, one piece of tape on the threader, one on the seat. Sure is an old eye saver and speeds up knot tying.
