For clarification, stropping on paper, under film, will polish the edge and about a third of the bevel slightly convexing the bevel to the edge and make a marked improvement in the shave. Stropping on Chrome Oxide, post .3um would be undoing the edge quality, CBN would be a better choice or just clean leather. Post 1um, Chrome Ox will show edge improvement.
