They say that you can never be too rich or too thin. But does that rule also apply to razors?

A week ago, I picked up a free sample of Schick's new disposable four-blade Quattro razor. I hate to say it, but the results were incredibly disappointing. Instead of the smooth, close shave I'm used to from my two-bladed razor (the Schick Slim Twin), the Quattro left my legs patchy and uneven. Boo!

So how is that two blades shave better than four? Why it's physics, darling...

(Cue the tinny music and fog machine -- we're about to have a flash back, people)

Do you remember a this equation: Pressure = Force / Area? Well, that's exactly why a razor with a large surface area (i.e. four blades) does not cut as closely as a razor with a smaller surface area (i.e. two-blades). When the force of your hand is divided over any given surface area, the pressure of the razor will decrease as the area increases. Translate that to your legs, and you get big surface area=bad shave.

So don't be fooled by marketers who tell you that more blades are better -- you know they're not.
