My standard reply for noobs: Norton Coarse/Fine combo stone. After some practice, this edge will easily shave my arm, and will catch hair on the back of my head 1/2" above the skin. Going slow and getting good technique is key. Don't rush or you will damage the edge accidentally.
Lay the stone on a table with good light. Put the knife on the stone with the edge facing you. Do not slide the knife at this point or you will scratch it. Lift the knife until you see the edge touch the stone. Use this to find your angle. It will match the factory angle. Take strokes toward you, 20 or 30 per side. After sharpening one side, check for a burr on the opposite side. I do this by stropping the edge on the back of my arm or head. A burr will catch and scrape the hair, and a smooth edge gives no pulling. After you have been able to get a burr on each side (not at the same time), move to the fine stone. Raise the angle slightly, and take alternating single strokes on each side to remove the burr. 10-20 per side should do it.
If you can cut accurate angles on wood, you can make all kinds of jigs/guides. I cut three 4x4s at 12, 17, and 22 degree angles. I then screwed each one to a 1x6 base. Now I lean my stone against the 4x4 and have a Sharpmaker like angle guide.
