Today I got one of those glass smooth shaves. I have not exactly pinned down what causes these incredibly smooth as glass feeling shaves. Anyone else know what I'm talking about? Today was my fifth I think, second ever with a straight razor. Besides a perfect, yet not exceptionally sharp, blade I did one thing a little different. I used a watery cream. With a DE (I used one of these for awhile last year) it was essential to build a good protective lather. With a straight I use a water only pass so a watery cream isn't a big deal but it never occured to me that it might be enhancing my shaves, thus I don't repeat the process too often. I'm going to try it again tomorrow if I can replicate it. Anyone else ever use this technique or know what I'm talking about?
