I have the Lansky system. It's Ok. The best way I've found is to get a stone with medium on one side and fine on the other. Hold the knife (or edge) at a steady angle and stroke, blade in, to sharpen both sides. Finish with a good paste on a leather strop.
I don't strop edge first.....it cuts into the strop. Strop edge last and you can shave with it.
