It's not going to get you a perfect knife edge, BUT it's not supposed to. What it will do is quickly, easily, anywhere you want, put a very serviceable edge on almost any camp or craft style knife. It will put a nice edge on most kitchen knives, but the preset angles aren't set for the finer edges of kitchen knives, so you have to work a bit for that usage. It's got carbide and ceramic sticks built in to get you from s*** to shiny in a few pulls on each side. Remember to go as few strokes as possible on the carbide side, as it eats a lot of metal off your knives.
