I like the idea, but the focus should be on overall knife quality, not the way they're made.
Maybe there should be an election / nomination, held secretely once a year, of 100 "knights" of the knifemaking crafts (the Round Table of knifemaking, if you wish). The knighthood would only last this one year, and would only be reflective of the work of the past year. Makers would get the right of a special logo / stamp for 1 year. Since the ballot would be open (members can vote in new candidates, and don't have to choose from a pre-selected list), new blood would get a chance at the front row. Because there would be turnover, there would be no shame in loosing your "knight" status. Many makers would "loose" their status due to a choice to produce more using friendly pieces, or to semi retire, or to focus on teaching, etc - no shame in this.
What would have to be pre-selected is the number and quality of voters. They should be high quality makers, collectors, dealers, etc.
BTW, "knight" might be the wrong term. Maybe "Ambassador" or "Intangible Asset"

would be better.
