Ban, that is very impressive. At first glance I did not realize just how much you had changed the grind. I'm not sure of the technical terms but I would say that you took the knife from a shallow saber grind to almost a full flat grind. Not only does the blade look 100% better, but I would imagine it is now a far more efficient cutter. Grinds are clean and straight. To me that is what it is all about. Again let me say that you did a really wonderful job. I would have no qualms about sending you one of my blades for refurbishing. Congratulations on a job well done.
