Do you have one of those insane three-to-five blade razors to shave yourself every day? I do. The razor itself is fairly cheap, but the blades, over any period of time, are damned expensive. I offer Harry's razors for those of you who have no time to do anything else but shave as fast as you can. They are high-quality, and, of course, replacement blades cost money. They'll do a good job, I guarantee.
There is another solution for those of you who are adventuresome: straight razors. I have two of them. Let me tell you, they are frighteningly sharp, so sharp, that stropping them with leather makes them more sharp (think about that). They are not cheap, but are readily available.
There are plenty of guys who use them. It's one of the best ways to maintain a pencil mustache, for example. The main attraction is that, even for you guys that have incredibly thick, heavy facial hair, a straight razor is the very best way to shave so that your face is totally baby-butt smooth. Ladies may like that.
Shaving with a straight razor is definitely not for everybody. You have to pay close attention to what you are doing, or you will cut yourself (I have, several times). You have to practice, and be patient while learning to use one. You have to have good beard preparation. I offer the best products to do that, and link to the best website on the planet for learning about straight razors.
Again, over time, using a straight razor is significantly cheaper than disposable razors. The blades, if well-kept, will last several generations, they are so good. You just have to take the time needed for a really good shave. Worth it, when you need a baby-butt smooth face (hope she is worth the effort!).
