Borrow a dremel. Tape down a cloth to cover the keys, ports, fan exhaust, and the monitor. Go along the edge with a grinding tool on low speed. Go along it again with a sanding tool. Finally, buff it. (All cheap parts in the default kit).

Wear a mask.

Also, the amount of grinding necessary to get a smooth edge is not much at all. This is a quick job, and leaves the same grey color.

Finally, there are covers that remove the hard edge.

Wow, that's tempting! Have you done this? Any downsides to speak of? How deep did you go? This seems like a great mod.

I followed the steps mentioned at http://dustwell.com/macbook-pro-sharp-edge.html

I basically just gauged it by eye. Light, slow, take your time.
