Yeah, I guess that's where I'm at. Angle? Haven't got a clue. I just do what Mr. Van told us: lay the knife edge down on the stone at 90 degree like we're gonna cut it in half, then lay it over half of that. Then cut that amount in half again, and then we're in the right neighborhood. It always seems to work for us, and got our scout knives sharp enough to shave newsprint or hair. Certainly good enough to cut whatever we had to cut. I've never had a sharpening gizmo in my life.
