I've never seen it, but a couple of things jump out at me.

1. Why? After spending all this time letting us know that he understands the blade geometry of a straight razor, and even laying it on a hone so we can see, why on earth would you then rig up guide arms and strap it into this contraption? Surely the easiest way is the way we do it - move the razor on the stone on a flat surface.

2. What if your razor has the variable spine width geometry that you see on a lot of the old Sheffield smiley wedges etc? This system seems to work on the supposition that the spine thickness (or in other words bevel angle) remains constant along the length of the blade. Is this "Wicked" system able to cope with the "rolling" stroke necessary to hone these kinds of razors?

3. It seems to me that pressure is an issue with this kind of ergonomics. In essence you are moving a heavy hone against a fixed edge. Of course, with some time and skill development I am sure you can develop a very light and even touch on one of these contraptions, but in my opinion it is a lot easier and more controlled to move the razor on a stone.

All in all, that thing looks fairly decent and clearly they have thought long and hard about its design and use. However, personally I will not be rushing out to get one for straights. If I owned and sharpened knives, maybe. But not razors. YYMV.
