I keep mine in an old wooden cigar box next to the sink, but I use gel packets you find in shoe boxes, and other items (I think it's silica) to prevent rust. I rinse my blades with hot water, when done shaving I dry them with a towel, run them on the felt and leather. I have two stainless steel blades I use mostly though. The rest of my blades are carbon steel, so I'm not sure how they would fair with this treatment.
