I just saw an article about a study at MIT where they are trying to find out why blades deteriorate so fast. So they did a bunch of Electron Microscope studies of used blades (DE types and cartridge types). They expected that blades would get dull by getting rounded off but like every straight user knows that doesn't happen. Blades quickly develop micro chips which rapidly get worse and worse even after one shave.

So they will be trying to come up with an alloy that will last much longer. It will cost much more per blade but you should be getting many more shave per blade. No dates for results.
