Back in the 80's I watched a science show on TV. They were showing metallic glass, a material which is a metal with a chaotic atom structure (like glass'). Samples looked like metallic measuring tape wchich tore like paper, but when sharpened, stayed sharp for very long. They said there was a patent for making razors out of it, they would be sharp for years. Reportedly, Gillette bought it so that nobody would ever use it.
I suppose there is plenty of materials of this kind, guess where the patents are...
