I have been wet shaving for a few months and have tried the Walmart, Merkur, Derby, and Dorco DE blades. I usually get pretty reliable results on the 1st and 2nd shaves with these blades. However, when I attempt a 3rd shave with any of these blades I notice a significant difference in the amount of drag I get and usually end-up with some irritation afterward. I don't mind that I only get 2 uses per a blade since they are so cheap, but I was just wondering how many of you out there experience the same thing. Does anyone else only get 2 shaves per blade before noticing a marked decline in performance, or do I just have abnormally tough stubble?
