i prefer diamond stones as they are less messy, DMT is my fave brand, get a course and a fine and extra fine, mark the bevel of the knife with a sharpie marker then do 2-3 strokes on the side you marked and see if you removed if not or only part of it adjust your angle tell you remove all of it then work that side for a while untill you form a burr (the edge rolls over to the other side, you'll feel it with your fingers) then repeat on the other side for the same amount of time, then go to your fine stone and repeat, then on your extra fine stone do 1 stroke per side alternating sides for a while, once done take it to a bare piece of un treated leather and use an edge trailing motion at a lower angle then you sharpened at, do this for 20 or times on each side alternating sides every stroke, by the time your done you should be able to shave with it. also theres a few good video's on youtube.
