I don't oil any of my blades carbon or stainless steel unless I am going away on vacation. They all get used once a week in rotation and we don't live in a high humidity area. Your climate may be very different. Yea, stainless steel is not impervious to rust but does so at a greatly reduced rate. I just looked at a stainless steel knife that had been sitting in it's leather sheath for a couple of years unoiled and it still looks new. Just saying there is much less of a panic about rust with stainless if kept dry.
