While as I have said I don't typically shave while on tour, with the mentions of shaving oil, soap, and shaving cream, I thought that I would mention that I have always shaved with just plain water. It seems to work fine and might be a little easier in some situations for those of you who do want to shave on tour. This may be especially true while in more primitive conditions where water consumption is limited the savings in water of not needing to rinse off after a shave might be helpful.
