I found a Schick injector razor probably five years ago, and bought a supply of blades for it off of Amazon for about $15. I really only use it for cleaning up my neckbeard, but I'm not even halfway through the blades I bought.
It does take a little care until you know what you are doing, since you can really carve yourself up with the single blade if you go too hard. But it's certainly sharper and does a better job than any of the multi-blade disposable razors I used to use.
