Recreate the basic edge

Knife Fig 1 If you were to peer at the point of a nicely sharpened, multi-purpose knife blade, it would look something like Figure 1. You'll notice that the blade is actually beveled to form the final edge, but you won't create that bevel just yet. First, you'll form the basic edge, which is a little simpler in shape, as we see in Figure 1A.

Knife Fig 1a One of the key points of knife-sharpening is maintaining constant angles between the blade and the stone. There are two: the angle between the blade and the edge of the stone, and between the blade and the surface of the stone.

Knife Fig 2 Turn the knife over, and repeat the process. If you keep the knife in the same hand, you'll be pushing the blade away from you this time. It's important to maintain the same angles on both sides of the blade. Go slowly and alternate strokes on the stone until each side of the blade has been stroked several times. A very dull knife will need a few more strokes than a better kept one.

Create the final bevel

Now that you have a basic edge on the blade, it's a time to create the final bevel. This will strengthen the edge, so that it stays sharp longer and is less prone to be damaged by everyday use. You'll create the bevel simply by repeating Step 1, with two modifications: use a fine-grit stone, and raise the blade a bit higher off the stone (the second angle) when you draw it across.
