Diamond Like Coating - why can't it be used on straight razors?
Diamond like carbon based coatings (DLC) have been used on tools, files, chisels and engine parts, not to mention surgical implements. Why can't they be used on straight razors? It'd vastly improve the hardness of the blade, not to mention make it smoother(0.1 drag co-efficient - better than teflon, course the spine wouldn't be coated). You potentially wouldn't even need to strop a razor that had a coating on it, it would simply keep its edge for years and years. This is already being used on some cartridge razors..
Note that this is a 5-10 nanometer coat. (is the blade even finer than that at the edge?,)
any reason why it hasn't been done (to my knowledge)?
