Looks like a REALLY expensive version of the Lansky sharpener.
I've had one for years.
great if you really don't know how to sharpen a knife (no offense meant - just stating the obvious). Also really good for restoring an edge that is badly damaged or really poorly sharpened.
Sypderco also makes a sharpening system that I have found to b really quick and easy to use - great for touching up an edge, or putting an edge on a knife with a blade in good shape.

I tend to use both - the Lansky to restore or set up a blade, and after that the Spyderco to keep things sharp.
