The Straight Dope: Are twin-blade razors better than single-blade ones? #AskCecil The Question: "Dear Cecil: Certain razor blade companies have been making claims to the effect that "two blades are better than one blade," and show an animation on their TV commercials to demonstrate the "twin-blade effect." Personally, I can't tell the difference when I shave with a razor that has one or two blades. My question is, is the "twin-blade effect" for real, or just so much advertising BS? Also, how many shaves is the average disposable razor good for? I read somewhere that all the razor blade companies use the same steel source for their blades. Is this true? If so, shouldn't all razor blades be of equal sharpness, and hold their edges for an equal number of shaves? — Mark H., Scottsdale, Arizona" The Answer: Well you can read it at http://ift.tt/2jLf3fI but it is worth noting that Cecil says he has never been wrong!
