I was telling a friend of mine about my first straight shave last night and how I was not looking forward to going out of town because I wont be able to use it. (Trying to get by with just a carry on)

He agreed that it is a shame especially because when I come back my razor will have dulled a touch. This did not make sense but I cant help but ask. If the razor is not in use there is no reason for it to dull......right?
