To me, there's a lot to learn thru repetition--even if it's hours and hours. As an apprentice potter, I learned that few things taught so much about form and efficient movement than having to throw a couple hundred of the "exact" same thing. Those were lessons that couldn't be learned vicariously; it was tactile and intuitive, so it required doing it to learn it. I take that attitude into this knife project. And one thing is for sure, this knife is so stubborn hard that I don't think I'm going to hurt it. If and when I tire of the project, I can turn it over or send it to a pro.
