bobh,

I like your signature.

I will say that the rest of that video has some amazing to me footage of an edge. while I have made thousands of knives, and only maybe 60 straight razors so far, I had to go to charlies razor makers meet in texas to see ron and his "scope of amazement" to be able to see edges like this, which convinced me to get this scope and setup to help folks learn to sharpen/hone. It has really helped me see things that I could never see and explained things to me that I sort of thought, but wasn't sure about.
