We had some friends in the other evening, and one of them, after a trip to the bathroom, asked, "Why is that razor in a cup of something?"
For many years, I don't know when it started, or who told me about it, but I keep my razor, in a cup with some olive oil in it. The blades stay sharp for a very long time.
The Gillette 4 blade in their now, I have probably used for a month, and it is still going strong.
I have the one of the razors that vibrates, and after shaving, I rinse it good, shake it dry, put it down in the cup of olive oil, and let the vibrator run for a short time, to get oil between the blades, and it is ready for my next shave. I rinse it under hot water prior to shaving.
I don't shave every day, so I don't know how many shaves I actually get, but at the cost of replacements now days, it extends the life quite a bit, and the blades stay sharper. My guess is that there is a coating of oil on each new blade that disappears after the first use. This puts it back on.
I remember my old Gillette "blue blade" gave me a couple of weeks of good shaves, rather than a blade a day.
I suppose any good machine oil will do, I have just always used Olive Oil.
