The original question that started this thread is a fair question. There's no "complete list" of makers who constantly strive for better blade performance. But, you've received some good leads here. As Tom Mayo said, you need to get out on your own, do you research and form your own educated opinions. As Daniel Winkler stated, cutting competitions and public demos are the best place to start, if you want all the B.S. removed from the equation. My experience has been that you'll find a significant number of makers who put out blades that you feel you have great confidence in and that you'll then gravitate towards the styles you like within this group. Some of these folks make knives that cover the entire spectrum from "primitive" for lack of a better word, to ornate and use the same metalurgical priciples throughout. The fancy or "art" part is up to you and your wallet, but it's still a cuttin' machine.
