I have done test cutting on hemp rope with mild steel and that is the kind of difference you would see vs a quality tool steel. This kind of extreme exaggeration does cast that side of the arguement in a poor light because it degrades the entire perspective.
That being said, you would assume since the man is making knives for much longer he would command higher prices. I find the whole materials arguement silly because that is an inconsequential part of most knives, especially the high end ones. What you are paying for with custom work is the experience of the craftsman.
A lot of people don't want a high finish on working knives, I find it just absurd because the blade finish is marred immediately in use as is the handle. Thus that aspect is not relevant to many. That being said, if the grinds are the same angle on the same stock then they will cut the same, if they follow the same heat treatment protocols they will have the same properties.
In general it is hard to argue (rationally) that some maker has such a revolutionary process that they get such a massive improvement in A2. This is a common tool steel which is still well used. Why not go to the industry and tell them you can improve performance by 1000%.
