All great points so far.
A few other pointers:
First tape the spine with some electrical tape. Second ink the bevel with a sharpie, now do a few laps on your King, you can easily see whether you are honing to the edge, this may mean using x strokes, rolling x strocks etc, also known as hoing gymnastics. If you are removing all of the pen, your good to go. Carry on using the same strokes until the bevel has formed the perfect apex. This is where the loupe comes in, look down the bevel and from the side, slowly angling your razor to see if there is any sparkles indicating that the bevel is not fully set. Once you can see that the bevel is fully set you can use other sharpness tests to clarify. Now that the bevel is set you can move onto your Norton to remove the previous stria that the King made, keep using the loupe to check that your on the right path.
If in doubt refer to post #4
