Been using a straight razor to trim the edges of my beard for years. It's the only way I can get both sides to look the same. I have tried shaving my face with it, but not quite so sucessfully, lots of nicks.
When I lived in Pueblo Co., I couldn't find anyone to sharpen my razor, so I asked the barber, he explained and showed me. Has worked well since then. Even so, when I can I get a specialist to do it. The key is to lay the razor flat on your stone, and draw it away from the sharp edge, the same number of strokes on each side. Then strop to take the feather edge off. That simple. Except that you don't use the stone for anything else. Just your razor.
