Thanks HNSB! I thought I was the only person left on the planet that pays attention to geometry! I do all my work by hand so it gives me time to shape and grind in detail. It takes longer but the lines end up where I want them to end. A grinder just gives too much chance of "oops!" I have a great number of rasps rat tails and files that I use. then onto sandpaper. It is amazing what you can do with files a coping saw and sand paper. I have yet to find a razor that I needed more than that to work with.
