   Well guys you can see it might work, think about the paper seperating 
and sliding out slightly when cut.  That'll be moving out slightly along 
the face of the edge removing material, should work although only 
sharpening one side until flipping unless the very edge surface of the 
other side of the paper is enough to do it.  Seems like it'd be marginal 
vs just using a can opener sharpener unless you just keep fine sandpaper 
with the scissors to keep them topped off.  With little pressure 
elsewhere it doesn't seem like it'd remove much except just at the edge, 
you'd still need to sharpen in a different manner once in a while.
   Generally mine are pretty far gone before I even think to sharpen 
them, I'd be cutting sandpaper for hours I think.
