Your paddle, should flex enough to reach the edge, unless it is very thin, like Kangaroo glued to a flat board. A hanging strop will easily flex to reach the edge.

If you think it is an issue, run a sharpie lightly on the edge of the razor, this will ink both side of the bevel, about a 32nd down from the edge. Then strop and see if the ink comes off. You can remove any ink on your strop with a paper towel sprayed with WD40, if it bothers you.

A single sheet of wet copy paper will flex enough, under lapping film to polish about one third of a bevel, from the edge down, thicker leather will flex much more. Do not add pressure that will just cause more problems.
