TTF jigheads rusting?

I bought a couple packs of TTF jigheads last week. threw them in my wade box, and after one trip, got home to wash everything (same day), and they were already rusting pretty bad. yeah, things rust in the saltwater, but I also had several gamakatsu hooks in there that have been in and out of the salt several times with practically no rust.



what's up with that?
