Re: TiB Tips and Tricks Correct. My own razor has both sides exposed, however. Some DE razors only show one side so that you can dull that edge and then switch it around without worrying about forgetting which side you shaved with before, others have both sides exposed. It's a matter of personal preference. If you have one that exposes both sides, I suggest marking one side with a permanent marker (I used a little bit of solder to mark mine) "I shaved with the marked side yesterday, so I'll shave with the unmarked side today." Most DE razors actually last a while; I just happen to like having a new blade, and they're cheap enough that I can afford using a new blade every time. You can conceivably use the same side of the blade 3-4 times before it's too dull to actually use. In that case, you'll go through a blade in a little over a week... that's less than a quarter per week for shaving. DE shaving turns shaving from expensive to negligible.
