The "taught strop, loose razor' Concept is valid, but from what I was able to get out of the translation of Honing the Nihon Kamisori is that the slack of a strop should be bent around the spine of the razor with the edge following keeping what is generaly a light tension of the bevel side. If you would see the illistration it becomes more clear. Your puttoing your force on the spine as you drag the razor and the edge is being put down on the leather with just enough pressure to straghten out the edge of the bevel. I know, confusing without pictures, sorry.

Just a thought, tinkersd.
