In a nutshell, single-blade razors are better cutting instruments, don't clog up, are adjustable, and cheaper, he says. "A Mach 3 costs $2.50 to $3; the average guy uses two a week. A double-edge razor costs only 45 cents a week. A straight edge, virtually nothing."Besides being cheaper, Dupont says that single-blade razors cut closer. The author of the article shares his experience, too.
I bought an old Gillette single-blade razor on an eBay auction after seeing the "Today" show.I've never tried shaving with an older single-blade razor, but this article definitely piques my interest in it.
The razor appeared new and much heavier than multiblade ones I've always used. It seems to cut slightly more closely but is much, much more comfortable. Several times I've had to check to make sure it's actually cutting.
By the way, the razor, with 10 blades, cost $25.
