Yes we understand the frustration Bud and KG's point is well taken. That being the case, Grepper's lighting instructions are very valuable. We've looked at many an edge and pronounced it slick as a whistle only to subsequently follow Grepper's lighting advice and then see our egos shrink in disappointment. Initially, we asked the same question as you did Bud "what's real and what's not?". First of all, Grepper teaches that lighting is unlikely to make something appear that isn't there. An improperly lit edge can help to hide things that are there though. If you take into consideration the likely geometry (shape) of the burr (and if you're looking at the correct side of the edge) it helps in confirming that. If something is protruding from the edge it will usually cast a shadow under the correct lighting conditions. Imagine that you were looking at the top of a round fence post, from some distance and straight down, the fence post might appear as only a small, dark, circle etched into the surrounding terrain. If the light that illuminates the fence post is shifted to the side, the shadow cast by the fence post will become apparent. When that shadow is cast it gives the image a more three-dimensional appearance and things become apparent that were not visible before. Just our 2% of a dollar commentary on this subject ladies and gentlemen.
