Also, there is a huge difference between what is seen in a single photo and what is seen live in a microscope. I hold the blade under the objective and yes, I tilt it. Sure, tilting changes the way that light reflects off the bevel. That's exactly why I tilt it, so that I can see the edge from all the angles.
