I picked up a slick plane at a woodworking store some time ago. It has a pair of round cutters that are used to knock the sharp edge off a board. It works great. I planed some 2x stock flat and square using my power planer, then used the slick plane to take the sharp edges off.
I figure by the time I was about halfway done I would have had the router out and bit installed, then would have had all the boards to do.
