Now working for me too. Before it was going to a blank FishingMagic page directing me to contact Admin as it couldn't be viewed.
I've read the article with interest. It wasn't what I thought it would be
although elements were - as recently mentioned in other threads. eg. The BBC Shark one.
How about in fresh water? Would they eventually rust out then too?
No, at least not in a freshwater fish's lifetime.
There are many different stainless steels, I'm no expert but I assume the non-magnetic steels are most resistant to corrosion. I'd try a magnet on various S/S hooks to gather info.
I asked a diver earlier today and was told a top quality scuba-knife will last about a decade before really bad pitting sets in.
I've a good stainless sheath knife that I sometimes use to cut fresh whole beef tripe for the dogs. Despite wiping straight after use, remnant digestive juices seem to have stained the knife quite badly - but it hasn't corroded, yet.
I have some #4 gold plated trebles I aquired in Sweden (Baltic pike). They would fit the bill if you want to try some, but they have whisker barbs - crushing them would cause that part to corrode quickly just as it does in black nickel finished hooks.
Another anomaly would be if a weak 'cell' between the hook, wire trace and brass swivel were to occur. Depending on water conductivity, more than pH, corrosion would then increase dramatically (boats have sacrificial zinc anodes) - so many factors...
Education, and a switch to one big fine-wire barbless single hook, would seem logical alternatives.
