The Economist has plotted the number of blades in disposable razors against time, and if current trends continue, it looks like we’ll be shaving with 8 blades by 2010.
Or rather, you might, but I’ll be shaving with 1. As mentioned previously, I switched to a classic double-edge safety razor. Many shaves on, I remain enthusiastic about it. Definitely better than even the Mach 3, and cheaper per blade too.
