KMFS Vantaedge?

[LarryG]

Anyone use a KMFS Vantaedge? It has an interesting way to fix the sharpening angle across the blade. Looks like high-quality construction also, with linear bearings. Overkill, or a good idea?

While I like that it actually maintains a consistent angle, the angles themselves seem poorly selected and I don't like that it isn't adjustable on that front. It seems far too limited in application.
