I think a pasted hanging strop does round the honed edges a little bit. I have razors that shave well that are sharpened on hones only, hones then pasted bench strops and hones then hanging pasted strops. I also have razors that I use coarse then fine hanging strops to sharpen. There are many ways to skin a cat. I enjoy trying different methods. All of the methods will get a razor sharp, I do not dwell much on what is happening at the edge, I just try a method and see how it shaves. Not every method works on every razor, every time, that is what makes it fun.
