I've no idea how much a razor "should" cost, perhaps you would enlighten us with your calculations? If I decided to produce my own razor blades, I suppose I would need to buy an iron mine, a factory to melt the ore to iron, and a factory to turn the iron into razor blades. And presumably hire a few industrial designers or engineers to ensure that I got a nice razor rather than a lousy one. I've no idea what any of these things cost, so I'll pick a random number and estimate a few hundred million USD. And say I did all that just to get razor blades for myself, because I thought the market offerings were too expensive. So my math is: Say $500m to aquire the means of production, an unknown yearly cost to keep them running (so I'll just ignore that part), and a consumption of one razor blade per week or slightly more than 3,000 blades in a lifetime (assuming 60 years, age 17-77, of shaving). According to my calculations, razor blades "should" cost in the neighbourhood of $160,000 per blade. That's my math. What's yours?
