jokrswylde, if you are buffing for polish effect, you need to go a lOT higher in your grit first - 1500 minimum.
Don't depend on that buffer to make things shiny! 600 grit scratches on a polished surface are practically gouges!
And, for a proper hand rubbed finish, and I don't care what anybody says, go up HIGH, and then come back down!
You don't just stop at 600, 800 or 1000, take it up to 1200, 1500, or 2000 and then rub it out at your desired finished grit.
Make full length strokes on your blade with backing for the contour of the blade - flat for flat, slightly flexible for hollow or convex.
Get comfortable - ready for the long haul. Don't go to the next grit until the one you're on is 100% complete.
There are numerous tutorials all over the web if you search.
What I've said here doesn't even scratch the surface - no pun intended!
