I think that it's kind of hard to claim any "proprietary" methods in knifemaking, though there are those who try. I can think of one person out there whom I won't name because first I can't remember it and second he's very litigious who claims all sorts of things that have been practiced for centuries and/or run contrary to the science of metallurgy. Of course there is no rule that if I used 52100 to make blades with or how I heat treated this somewhat tricky steel that I have to say so.
There was one maker who developed a method of producing a blade with a bainite spine and a martensite edge. In a post he explained that he wasn't going to post the method on a web site because he had spent many hours perfecting the method. He wasn't opposed to other people using it, or spending the time to research and develop the method for themselves, he just felt if someone wanted the technique from him they could do him the courtesy of making arrangements to come to his shop and and letting him show them the method. Other than that there is not much about knife making that's new under the sun.
Old age and trechery will always overcome youth and ambition.
