I'm not sure I can agree whole heartedly that more expensive knives actually perform "less" well. All of my mid techs out perform my production knives...all of them. With the exception of my Spyderco Gayle Bradly....geeze that thing is quite the tank and holds an edge forever! Buttery smooth too.
But I will say.... My mid techs, they hold an edge much longer, they have better fit and finish and (most all) have better blade steel. What you get with a mid tech or custom is someone spending more time on it to make sure the details are perfect or very close to perfect.
Don't forget the heat treat, just because 2 knives have the same blade steel doesn't mean they perform the same. Heat treat can make all the difference in the world, ask any maker. I'm sure the production knives have a decent heat treat....but sometimes blades have to be soaked and quenched various times to alter / optimize their molecular structure. Do you think production knife makers have the time to do this... Even if they did have the time, it's not cost effective. I think in the end (with a mid tech) that's what you are paying for..... Total time involved for the maker.
Yes it makes a difference in the performance! Performance isn't just how sharp a knife can get, it's about how smooth the pivot stays after you "hard use it" It's about how the lock up and or the centering doesn't change even after a few years worth of "hard use" it's about how sharp it stays after you've cut drywall or broken down literally tons of cardboard boxes (ps, please use a drywall saw for cutting drywall)
Ok, the "willfully blind" thing.... I think what you are trying to say is that maybe people are kind of seduced by the more expensive knives when really there is no merit to them?? Sure, I think there are some who buy just for the name recognition or the cool factor but it doesn't change the fact that the knife in question (whichever mid tech it may be) is still a better built knife.... Better materials, better fit and finish.
For individuals that buy them...it is their prerogative and like it's been previously stated, If it's worth it to them.... then it's worth it.
Not trying to stir anything up, just didn't completely see eye to eye with you.
Carry on
