This. I shave with water and a mach-3. Have used this technique for over 25 years. Can't think of a time when I've had razor burn. I can't recall the last time I cut myself either. I even go against the grain at the end (people who witness this seems to cringe). I hate shaving and do it once every week or two though. I'm blessed to have very slow growing face hair. My blades last a really long time because they're almost never used.
