I just did a google patent search for the edge pro, just to see what it came up with, and I found it. with enough clicking, I found the new TriAx, too.

If you look at the bottom, you can see other patents which the current patent is "related" to, and also other new patents which have cited the current patent. Pretty neat to see the evolution of sharpening apparatuses over time.
P.S., don't call up edge pro and ask to speak to Benton... he goes by Ben.
P.S.S. I could only find the "Pro" model of the edge pro, and not the apex.
