Kind of a goofy little problem, but here it is. I want to shave with my EJ one day, my Gillette Tech, the next, my Gillette adjustable the next and so on and so forth. I kind of like moving my blade from one razor to another every day. I feel like I should probably get 3-4 shaves from one blade before I get a new blade. Other than the minor inconvenience, is there a down side to doing this? I read something about altering the tension being bad at some point in the past, but I'm not sure I'm buying it. Any thoughts on this? I'm sure I'm not the only one here to change razors from day to day.
