Nate,Thanks for your information and pictures on the rust removal!From the pictures you posted the file looks like the new steel gray colour that files seem to have when you but them new.Wonder if lemon juice would work is it not acidic as well.I think that I heard of using a cut side of lemon to rub on carbon steel knife blades to remove rust.I am not positive on this tip as I have never tried it. If anyone wants to correct me, feel free to do so!Rust was one of the main reasons they quit using carbon steel blades in the meat industry,as when I started in that line of work there was still a great number of manufacturers still using carbon steel.We used to keep the rust at bay with mineral oil.As the years passed stainless steel was getting better at holding an edge and was introduced more and more in the industry.

I would take a carbon blade over a stainless blade for sharpness any time, but in the food industry they have to be careful of contamination etc.
