It rusts if you have acid skin(I do)
I maintained my daily carry Large PocketWorn Amber Bone Case Stockman, religiously, and it still got rust spots and dull.
I prefer the med/large stockman pattern to all other jack knife multiblade patterns, for me it is just the most useful. In a Case model, I get SS, in the others, which I do not carry daily, it is pretty much get what you want. Some do not offer a choice of steel.
I carry a cranberry bone Case sowbelly pattern, it might fit your uses, Boink. I keep it in my jacket pocket in a William Henry Clip Case, it keeps the tobacco from my cigarettes out of the body
I also ALWAYS reprofile the blades on my stockmans'(stockmen

)
None of the manufacturers really put a shavin' sharp edge on the blades anymore, and the points are usually not pointy. Currently, I have examples from Case, Queen, Carl Schlieper, Cold Steel, Bulldog Brand, and Fightin' Rooster. You might not care, but I thought that I would warn you. You can get an idea of what you really like from the Smokey Mountain catalog, and then purchase there or online. The German models are my preference, but they can be fingernail breakers right out of the box.
For an SAK, I daily carry a black Climber, which has the scissors, and package hook.
