And you asked "why?" And I gave you my professional opinion. Because that is the question--why? The response to my answer (post #611) was just contentious misdirection and beside the point. At some level if he's a shoemaker and doing a repair with techniques that are for repair purposes only and / or not part of the Traditional "lexicon," he's not making shoes. Nor is he functioning as a shoemaker, really--and that's personal opinion...(albeit with decades of experience and knowledge to back it up. Take it for what it's worth). And FWIW, I don't know who the "maker" in question is, nor do I want to know. I am speaking about a technique--it is / was an analysis in response to your "why." .
