Razors were a common daily use item. The were treated with the same care as you treat your tooth brush now. It was an item to be used until worn out then pitched and replaced. You could get them at the local hardware store for a dollar. Things like this were viewed differently back then. A straight was common, used by many and available everywhere. If you simply dry the razor after use, it will keep for a very long time. I never oil any of my blades and only occasional give them a polish. Still mirror perfect. A little or a lot of pantina was not any more of a problem then a dirty handle on your hammer. In fact, a good hammer was probably cared for better than most razors since you needed it to make a living and keep your house and barn from falling in.
