Interesting. The instruction manual on my new gizmo says 20 degree knives are ok and it will change them to 15. I suspect it is because it has diamond grinding wheels so wear on the wheels is not a huge issue but I'm guessing....... The "finish" stage of the sharpener appears to be a ceramic disc which I suspect is kin to the disc Tracy uses.
