Diamond Coated Razor Blades Developed in Germany
According to Design News:
"GFD Gesellschaft für Diamantprodukte of Ulm, Germany, is pitching the idea of using a super-sharp razor blade made of industrial diamonds that could last more than 1,000 times longer than today's conventional blade.
A nanocrystalline diamond coating is first applied to a carbide blade, then the minute layers are polished by a plasma sharpening process developed by GFD. The blade is polished until the cutting edge is sharpened to only a few nanometers, consisting of merely a few atoms."

To De Razor, no. diamond cutting blades like concrete ones use industrial diamond bits embedded within the blade, and as the metal wears down the diamond bits stick out and act like sandpaper. These razors are standard carbon steel that have a diamond coating, like icing on a cake. the coating is then sharpened. So no steel actually contacts you, just the diamond edge.
This intrigues me. Having recently discovered the incredible sharpness of ceramic knives, I've been wondering if ceramic razor blades might be the next wave of the future, but this sounds like another step beyond.
