There are companies selling ceramic kitchen knives. Has anyone tried a ceramic razor blade? (I see there is a ceramic blade razor prototype floating around on the web.) Amazingly, I did find a source for ceramic injector razor blades: http://www.specialtyblades.com/materials/zirconia_ceramic.html They claim blade life as high as 100x that of steel. But they are pricey in small lots -- $14 each in lots of 10. (How many "last forever" blades do you need? 10? 50?? 100? 1000?) P.S. I personally feel safer with a not too sharp blade. These ceramic jobs are super sharp. (They don't give a sharpness rating if such a thing exists. ) P.P.S. These are not your ceramic coated blades.
