I highly recommend the green chromium oxide liquid and powder, as well as their Diamond Spray from Hand American . I have used the compounds from Bark River and just about everywhere else, and while they all work well, none of them are in the same league as the Hand American products. You really don't need the Diamond Spray unless you want to just get ridiculous with your edges, and I only use it on hand strops. The green chromium oxide liquid and powder I use together on my leather belts as well as hand strops and it is very nice!

You need to be careful with the leather belt and don't put a lot of pressure on it or you will round over your edge. If you will try working with the knife closer to a more supported area of the belt(just below top pully or above the platten if you use one) you don't get as much "flop" action in those areas.
