Has anyone heard of / tried out the XCBlade runner?

Looks like the blade flares out in the front and back ends of the runner (like the Flare Skate blade runner), but remains thinner like a traditional blade in the center.
Interesting technology, but it seems like a drastic change and might put your skating mechanics all out of whack.
Also might be a bit complicated on the sharpening/profiling end of things.
