I disagree about SR-101 being rust prone. It is true that it rusts easier than INFI, but I have been using a Battle Rat which is made of SR-101 here in hot, humid, rain soaked South Carolina for 4 years how without any problem with rust. All you have to do is clean it and dry it when you are done using it. I also normally put a light coat of wax just on the exposed metal before I put it way and ta-da, no rust.
