Stropping will not sharpen a dull blade. It will true up and smooth out an already sharp blade. You need someone experienced in sharpening razors with the right tools to do it. Hit the vendors section and send it off to someone to do the job. Make sure you really study stropping while it is gone so you don't roll the edge right away. Spine and edge laying flat, spine leading, no pressure to speak of(enough to keep it flat).
