I'm not going back to carts until they add that all important 5th coating...UNOBTAINIUM! Until then, I am happy with my DE's and SE's.
I can't seem to find a link to the commercial. For anybody who's interested, below is a snip from their website that shows us what coatings are being used. Notice the "diamond-like" carbon. Sounds like something related to pleather?
It might be this old thing, from http://www.pgdermatology.com/downloads/documents/Gillette_WhitePaper.pdf dated 2009:
That was originally about fusion blades, but they could presumably apply the same technology to any blade. Using DLC for hardness seems to be http://www.google.com/patents/US5142785 from 1992. In 1994 http://www.google.com/patents/US5295305 seems to cover Gillette's use of Niobium and other binding agents between coatings. I think that first patent has expired and the next will expire soon, so we might start to see other blade companies using DLC coatings. Of course, those blades might cost more.

The 4 coatings thing is interesting to me... we all know for a fact that coating the blades in different ways makes them perform better/differently.
Saw Tiger in a golf tournament this past Monday with some stubble on his chin, which is how I've seen him more often than not in the past 2-3 years. Gillette must have had some good weasel words in that contract to get out of it after Thanksgiving, 2009.
Not to side with Gillette, but Diamond-Like Carbon is a real coating and it's good stuff. It's used often in the knife industry as a blade coating, though more to prevent corrosion than promote edge retention since you grind through it when you sharpen the knife.

Since synthetic diamonds can be created form graphite, which is also used for making pencil leads, does that mean we can just just a pencil to draw on a DE edge. That would be diamond like, right?
Sounds like a very good business move which may help them make more money in tough economic times. Isn't that what corporations are supposed to do?

P&G has a poster.pdf entitled, "Innovations in Modern Blade and Razor Technology", in which they state that the Gillette Fusion is beyond scalpel sharp. I'll take their word for it. Scalpel sharp generally means the scalpel is apt to dull more quickly than so-called razor sharp. So, they have added a DLC layer over the stainless steel "substrate" (i.e., stainless is now just a layer under some carbon fluoride). This sort of reminds me of the article that came out back in the 30s that claimed Gillette blades were so sharp that the edges of their blades were invisible because they would not reflect a single photon (I'll take their word for it). Unfortunately, these claims tend to sound a bit bombastic. What next?--proprietary dmso-containing beard conditioner to help dissolve keratin from the root up?
