Haha, I saw a special on the history channel about sharpens and blades and they talked about ceramic blades. Ceramic blades supposedly can be sharpened much sharper then steel, and are used in industrial applications where sharpness is demanded and low risk of impact, eg slitting applications. And of course because it is ceramic the edge will hold longer because the material is harder.

I read somewhere that you can have an edge that is "too sharp" for a razor. Instead of cutting hairs and riding on the surface of the skin it will slice into the skin. I think that oldblades can testify to that
