"As far as using a carbon steel knife in a shipyard, wrong tool for the job. You just don't maintain it properly. Ships are not made with stainless steel and last a long time, so what's the answer, maintenance." LOL. I've been biting my tongue for a long time but this is too much. Here's another bit of reductive logic: Ships are made of carbon steel and they float, therefore steel floats. You ignore the protective paint, constant replacement of parts due to corrosion, teams of men working on them, and that ultimately the sea always wins.
It is generally accepted that carbon steel does in fact rust and rusts easily. Strangely, there's a lot of people on here that would argue that fact until they're blue in the face. They'll tell you in one sentence that carbon steel probably shouldn't be used around salt water, BUT ships are made out of it so if your knife is rusting well, that's your fault. Others will tell you that you just need to rub it the right way or that mineral oil is all you need to protect your knife forever. So, if your knife rusts then well you've probably never maintained a knife in your life.
This of course ignores the experiences of everyone that has maintained their knife, lives far from any coast and yet at the end of the day still finds the red enemy spreading across their blade. The truth is mineral oil dries out and gets wiped off easily in use, rubbing your knife does not give it magical anti-corrosive properties, and carbon steel is fairly reactive to the humidity and crap that it gets exposed to on a daily basis. Rust happens, even to responsible knife owners. I hope this isn't too much of a shock to anyone.
There is no one best steel out there but 1095 is not ideal for pocket knives. I like the tradition and I know it's easier to machine and I know that's why GEC uses it. I wish they would make more in the GEC line, even though I know that's a pain in the butt for them. Their 440C knives are excellent and with today's market they'd sell like, well they'd sell like GECs. I appreciate the knives and I will buy more 1095 in the future but yes I do wish we could get some really great knives in Elmax or if you still want a patina M4.
