No, I didn't, because I was being silly, not serious. I had in mind for one of the big razor companies to sell it as the hyper-warp-13, or the Dreadnought or something, but I was still joking. If you can get carbide utility knife blades, someone probably did try it for razors.

That said, I'm dubious anyone has worked out an economical way to bond tungsten carbide to steel that small and have 3-5 strips of it in a cheap disposable head. Margins on razor manufacturing are, pardon the pun, thin.
