All of the above posts give you a wide range of choices to prevent rust on your blades. For the area where the blade is attached to the handle at the pivot, occasionally put a drop or two of fine grade oil there. It will prevent water from getting at the metal in a spot difficult to reach. Some of the old timers swore by the technique of soaking the blade in oil once a month or so...or putting a heavy coat of oil on the blade and let it sit overnight. Supposed to soak into the pores of the steel? Who knows...maybe just an old wives tales passed on to their husbands. 8)
