Bill:
If I could elaborate afrom an amateur perspective, that angle is one of the reasons that I have suggested carefully marking the sharpened portion of the edge with a Sharpie or some other marker to see how much you are taking off and where.
If as you sharpen, you see the color of the marked edge is not being removed uniformly, you are changing the edge geometry.
On a really good knife that comes sharp, the factory edge is probably where it needs to be to do what the blade is designed for. The edge geometry on an axe will not be the same edge as a machete, or a pocket knife, or a straight razor. Most good sharpeners have the ability to change edge angles to suit the design of the individual piece. It might even have a compound angle, or serrations, which can be a real bear to maintain.
Once you have the right angle for sharpening the individual blade, try to maintain it during the remainder of your sharpening.
HTH.
