That's not true, and Sal Glesser would be the first to confirm that - and has actually posted to that effect. His posts are quoted elsewhere in this thread.
OTOH, Sal is a classy guy who is wise to not trash (rightfully) respected knife makers. I think there is some truth to the idea that modern methods are closing the gap between some much lower cost production knives (perhaps some Spydercos) and CRKs in terms of tolerances. To your point, Sal will never likely make any such comparison between Spydercos and CRKs. Simply put, Spyderco, CRK, and many other companies make some GREAT knives that are good fits for different buyers. No need to compare them, rather enjoy them, celebrate their differences and buy what suits you.
Worth and value are something that perhaps should be left to the end user/buyer to rule on.
There are people who would (and do) spend MUCH more than USA retail knife prices (CRK, Spyderco, you name it) due to where they live and delivery/exchange rates/customs/etc issues. These people are shining examples of how value is dictated by the end user/buyer.
I would not ignore the fact that the "tolerance" argument is diminishing over time. There will come a day when production knives will have tolerances as tight as CRKs. I would not expect this to diminish the asking price of CRKs though...there is more to it than that, and people have to figure that out for themself.
It is a concept not unlike custom knives. I have several that look like they have been dragged behind a truck because they have been used very hard. They cost a pretty penny, and they were not bough to look nice. I do not attempt to explain their value to others...not because I can not explain it, rather because they can not understand it.
If you find something that works for you that is better than anything else you have ever tried, you might know what I mean.
I can only suggest that people think about some concepts and decide for themselves what sort of value things hold to them. If I look at a piece of art and I like it, I think to myself, "what would I pay to own this?" then I find the asking price. If they are asking lower than the number in my head, I buy.
Knives can be similar in this regard, but they are functional. It is difficult to assess this functionality before buying, and not everyone will enjoy the functionality in the same manner...thus (I believe) we see threads like this were people are polarized for and against some knives.
