I have only been using a straight razor for a couple of months now. I can shave most days without nicking myself, but I don't get a real close shave yet. I travel a lot so a few weeks ago I bought a Dovo Shavette to use while I'm in a hotel. I get an unbelievable close shave with the shavette but I end up nicking and cutting myself every time. I also experience razor burn with the shavette but not my straight razor. What am I doing wrong?
