It's all in the name

I hate shaving! When I do, though, I use Gillette's Mach 3. It has three blades. It gives me a close shave and I'm happy with the results. I know there are some razors out there that have five blades. Do I really need to upgrade? Will the extra two blades give me a smoother shave or will I lose more skin?

I noticed recently that there is a Mach 3 Turbo (see image). What exactly does the word "turbo" have to do with shaving? Will I be done in eight seconds? Does this blade, like its internal-combustion engine namesake, have a compressor to increase the power output by increasing the mass of oxygen and fuel entering the razor? Do I need to work out to hold this thing?

Bloody marketing!
