I don't know where you get your numbers from, but I am a blade smith, part time self employed as such, and I can guarantee you that it does not take a week to hammer out a knife. Starting from steel stock I can hammer out a proper blade in about 20 minutes by hand. Even doing something fancy and making a multi layered steel knife with moderately complex steel patterning can be done in under a couple of hours.
Filing, grinding, heat treatment, polishing and making a handle take longer. Even so, if I apply myself I can get a multilayered knife from stock to finished knife in less than 8 working hours (need to allow time for tempering and curing of expoxy) if I want everything to be crisp and show quality. At the last gathering I went to I made a small multilayer knife for a friend in under 5 hours, though I admit the polishing before etching was not up to my usual standards simply due to lack of time.
I grant you that this does not devalue the gist of your argument, but if you throw out numbers you have to keep the realistic. The above numbers are just for my skill level. I am good, but not like professional smiths of old. I've once seen an 85 year old guy from Sheffield forge blades like you wouldn't believe. He could crank out close to 400 fully detailed pocket knife blades per day.
