Most grades of non-"stainless" steel don't rust at any appreciable rate in dry air. If it gets wet, you have a problem, but it's probably safe in that drawer for as long as it takes you to find a professional to do the reblueing. The thing to worry about would be temperature and humidity swings, which might make droplets condense out in the crevices.

(This is why, for instance, an iron pipe left outside will rust where it touches the ground, where it's damp, and not on top, where the sun dries it out.)
