This is excellent advice-- any light weight oil (3-in-1 Oil, Hoppe's Gun Oil, etc.) will keep the rust at bay. For storage purposes wrapping the blade in brown paper works as well as cloth. If swords/dirks are on display (or are frequently handled) waxing the blade will offer more protection than oil.
