When I shaved this morning I noticed something consistent between this 'I resharpened my razor' shave and the other shaves I've taken in this new world. I'm delightfully wonderfully smooth after I shave.

But as I drive work, my face becomes noticeably stubblier. And it's demonstrably time based. When I get in my car, I'm still pretty good. But by the time I get to the office, I can feel lots of stubble.

Clearly, this is user error. Is it more likely to be error in face prep? The shave? The (lack of) post shave treatment? All three? Where I should I go look first? Note that I don't have this issue with the cartridge razors, so I knows it's technique and not biology.
