Interesting info Paul, You and I use completely different nomenclature regarding primary and secondary bevel definitions. Yours is probably more widely accepted than mine (I think I just dreamed mine up based on what makes sense to me). Now that I think about it, yours makes quite a bit of sense.

On another related topic, I have a fundamental hangup of calling anything a micro bevel if it is visible to the naked eye. This is why I call it a secondary bevel. In the end, your nomenclature names the bevels from cutting edge up, and mine seems to go from spine down.
As I said, I am inclined to believe that your nomenclature is correct, but wanted to offer the anecdote(s). Perhaps I need to go studying...it would be nice to have this in the edge-u-cation glossary perhaps so others will not build their own definitions as I have.
