In my last post I said to put the razor away and fix it tomorrow. Using a DE or SE razor never occurred to me, but it is a valid option. I have used a DE three or four times this year so using them is not something I would usually think of. In fact, I have given away most of my DE blades (I still have a few polsilvers, feathers, and nacets though).Good to know that you more experienced SR shavers still have to use a DE every now and then to clean up @Koop and @Frank Shaves.
It's funny, I'm feeling my throat right now and I'm not super pleased. I should have used my DE to finish it!
I guess it depends on what you consider and appropriate shave. Usually if the shave isn't going well, I would go to a SAS then leave it. No one really notices aside from yourself. The next day the shave is usually back to normal.
