Moore's Law For Razor Blades?

BartlebyScrivener writes "An article in The Economist examines Moore's Law as applied to razor blade technology: 'For the most cynical shavers, this evolution is mere marketing. Twin blades seemed plausible. Three were a bit unlikely. Four, ridiculous. And five seems beyond the pale. Few people, though, seem willing to bet that Gillette's five-bladed Fusion is the end of the road for razor-blade escalation. More blades may seem impossible for the moment — though strictly speaking the Fusion has six, because it has a single blade on its flip-side for tricky areas — but anyone of a gambling persuasion might want to examine the relationship between how many blades a razor has, and the date each new design was introduced'" I'm legally obligated to mention the Onion article that predicted this.

I found the trick a long time ago: you wash your face first to strip off the natural oil, then put another layer of soap on... if you do it that way, I doubt it will ever feel "rough". I just shave with the same bar of soap I clean up with (I'm not sure if it matters, but I use an odd Aloe Vera soap, put out by Grisi, a Mexican company).
