I stripped my BK2 and am in the process of sanding it, mostly because I'm friends with a lot of hippy outdoorsy people, and I don't want to get **** about my scary black knife. Something about stripping the coating makes it much less intimidating. It will rust, but I've heard people raving about tuf cloths, which I plan to try when I'm done. So far I've made some mistakes (my sandpaper was too fine and ended up starting again), and I'm also being pretty picky, but it's taking me a long time (but then I'm doing it in short stretches -- don't have a long chunk to dedicate to it). The key is to start with a low enough grit and move through them slowly and without skipping too many grit counts. Or that's my experience. It seems like other guys on this site move through the grits much more quickly than I am.
A good progression is 150, 220, 400, 600, (800 if you want), 1000... and then you can stop. Or stop before that. Or go nuts, make a mirror and work all the way up to 3000. It's all up to you. If you want it perfect and are super worried about scratches, sand in a 45 degree pattern, then 45 degrees in the other. Don't stop until you can't see any of the scratches from the previous direction. When you can't, move on to the next grit.
If you don't have a bench or a vice, screw the knife to a board through the screw holes, and clamp the board to a milk crate, then stack the milk crate on another milk crate. That's what I'm doing. Lemme know if you want a pic and I'll post when I get home.
Search through the forums and you'll find tons of info, including my way overly detailed plan, which I only half followed (and regretted later).
Good luck, and as always, pics or it didn't happen!
