...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.Of course this story from The Onion anticipated real-world developments by over 18 months.
This relationship (see chart) suggests shavers are going to get more blades whether they need them or not. However, just like Moore's law -- the observation that computer chips double in power every 18 months or so -- it seems that technology as well as marketing determines the rate at which new blades are introduced...
...So what does the future hold? With only five data-points, it is hard to be sure exactly which mathematical curve is being followed. If it is what is known as a power law, then the 14-bladed razor should arrive in 2100.

Moore's Law for razor blades:
