Ideally you should keep the edge of the blade that's in contact with the sharpening rods parallel to the surface that the sharpmaker is on. This means changing the angle of the knife itself relative to the surface you're working on while moving down the sharpening sticks. It's slow; it's awkward; it takes more patience than most have, but it's the only way to really get the results you want. If you got the sharpmaker DVD, watch it. If you don't: get it! There's a lot of extremely useful information and techniques in there that are invaluable to know!
I'd like an order of BUTTER with extra BUTTER and a side of BUTTER!
