A gent on here was kind enough to PIF a single edge gem razor. Naturally I'm curious however I know nothing about them . For example what blades should I get/try for it? Does it differ much from a DE razor? Easy to slice up your face than with a DE... Anything else I should know would be great. I've heard some folks talk about how they really like them so I always wanted to try one. Now one is on the way and I need a bit of guidance.
