Depends on the grit of your belt.
If you check here:

You can get the 320, 500 & 1200x grit belts. The 1200 leaves a nice finish on its own.
If you want finer then snag some of the 15u belts & then the leather strop belt. It leaves a wicked edge. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
That is the setup I use to fix up my blades after they get worked out! <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
