I just started shaving with a str8 and i was wondering how i can keep my razor from getting rust on it.. I shaved for the first time about a week ago and had to wait for a strop. There was no rust or anything on my razor when i shaved today about 15 hours ago.. i set my razor out on the sink open on its side kinda so if there is any water left it will drain out.. but when i just looked at it now there was some rust where the pins are on the scales. what can i do to keep this from happening..
