It's been a while since I had to do this on any kind of scale, but a small diamond whetstone works great on the edges of PCB's to get rid of the bumps as well as the nasty rough edges. It can be used with water to keep the dust down.
Working with a PCB that has the edges smoothed in this way feels a little bit decadent, but it sure is nice not to have them grabbing back with those fibers.
