Unfortunately, this is really more of a muscle memory thing. If you take your time and try to get a smooth, steady stroke every time, your body will eventually learn how to do it on its own. However, when learning you have to be fairly careful you're getting it right. Early in the thread it was recommended that you keep at least half of the blade on the hone at all times. I would have to second this as a good way to keep it level and let your natural dexterity learn the technique. After you have it dialed in (and don't jump the gun on this) you can begin to pick up speed and make changes to your strokes from things like thin hones and smiling blades. Take your time, be patient, and don't overthink!
