Now open mind is one thing, but not every unorthodox idea is worth pursuing.
Here's the problem. As Stefan posted in post #157, every single member who is moderately competent at honing and has used man-made hones has already done this. We all know what kind of an edge a 6k hone produces (we regularly take razors to the limit of this hone, just before the steel starts breaking off into a burr), what kind of roughness a broken off burr produces, how much drawing the blade over soft material (weathered wood, balsa, cork) dulls the edge, how much several stropping passes on paper smooth/sharpen. We know from our own experience what the method does.
The only people who are willing to test this 'new method' are the beginners who have never done it before. For the rest of us there is nothing new on the face of it.
Now, may be there is some special ingredient that makes it work for Mr. Carter, but he does not articulate any such trick. Or, may be it's just something one learns after practice, but to motivate any of us to put in the time, Mr. Carter will have to demonstrate that the end result is worth it, i.e. the edge his produces favorably stacks against what we're accustomed to.
Or, given the steep angle, and the amount of pressure in Mr. Carter's shaving video, consistent with the edges we can produce off 6k level hone, it is much more likely that 'his method', just doesn't work as well as what we in the straight shaving community use.
I can tell on my face the difference that my vintage cordovan strop makes compared to another or my strops, that's the level of sharpness we are talking about.
Again, this is something that probably every single one of us who have honed over few hundred razors has experienced.
