Found this paper written for tHe Law School of the University of Chicago and thought it would make interesting fodder for discussion. I take no stand on its assertions but pass it along for your consumption and thoughts. See it at below link. Interesting discussion of Gillette, his business model and some "facts" about all of these. Does this hobby have any limits to its fascinating details? http://www.law.uchicago.edu/files/file/532-rcp-razors.pdf
