Measure Hook Angle

So just set a protractor somewhere in the pic in any random spot, take a pic, and put it in a book. Then look on the back of the grinder at that "protractor"!!

This help?

I believe that the original photo was just to show the items used for measurement, not necessarily how to use it for a specific measurement.
