Beyond reducing your plastic footprint, this method of shaving is substantially cheaper - albeit with some upfront costs. I switched years ago, and paid about $150 for a nice weighted blade handle, brush, and soap dish and now I spend maybe $60 a year on new razors and soap. The one draw back I can think of, aside from the fact that you have to learn how to shave like your grandfather (which isn't really a drawback, if you ask me) is that you can't bring these razors through airport security in your carry-on.
