Well, I didn't find a whole lot on the web either. What I'd heard about hooks falling apart was mostly from friends and on one occasion, a Chesapeake waterman.
There might be a way to make them work, however, and that would be to make the hook out of two layers of material--some sort of fast-oxidizing metal as a sheath(microperforated) and something synthetic that reacts to long-periods of moisture by swelling. The result would be, as the water penetrates to the core, the interior of the hook would expand and crack the outer layer, causing it to fall apart. Of course this would probably cost a too much to make it feasible and end up either not working most of the time or poisoning the fish.
Thanks for the responses.
