I've been using 250 grit sandpaper and then 400 grit for a really smooth edge, gum trag to slick and smooth, beeswax to seal and fill any crevices where the trag might separate, and then a couple coats of atom wax. I've found this gives me the smoothest results. I had issues hand burnishing edges before since you have to either apply pressure or go really really fast to get enough friction to get enough heat, and that either tires your hand quite fast or will push your edges over, but after I bought a little Dremel and wood burnisher attachment my edges are turning out great.
