I've got about 15 straight shaves under my belt (well, not literally under my belt, just on my face), and I would say one of the most important aspects of straight shaving, compared to shaving with a double-edge and especially with a multi-bladed abomination, is the importance of skin-stretching. I didn't stretch my skin with a DE and I was able to get a pretty decent shave. But with a straight, the difference between stretching and not stretching is pretty significant. Stretching the skin will not only give you a much closer shave, but a far more comfortable one as well, especially in the neck area.

As for just starting out:

  1. After lathering up, lay the blade flat against your face
  2. Slowly lift the spine off your face as you move the razor downwards until you feel the edge start to cut your beard. That's the angle you want to try to maintain.
  3. Keep the pressure very light!
  4. Stick with one with-the-grain stroke for your first time out, even if it means leaving more stubble than you like.
  5. Try to get the hang of the proper razor grip...it feels awkward at first, but it very quickly becomes very natural and it really is the best way to maintain a good, stable grip.

Good luck!
