You have to get up mighty early if you want to beat Mr Rupert to the punch! I'm continually amazed with the things he finds and shares with me. Exactly as he did with EOU, actually. 
I've spent a couple hours researching this. Text messaging with Work Sharp finally got me in the ballpark. Indeed, there is some sort of carbide wheel that dents the blade. That seems to be the crux of the entire concept. After sharpening, the blade is uniformly dented on the carbide wheel, then you just touch up on the ceramic rod again.
If you have to start with a sharp knife, then dent it, then resharpen it, are you you actually gaining? If the dents are only around 5 microns deep, that would be like 3,500 grit "teeth", while it looks like they are closer to 35 grit dents.
I'm sorry, but it seems like something is not adding up, IMHO.
