Very interesting reading everyone's responses to this topic (especially my own, I'm that important!

).
I notice the discussion of shoes, sheets, beds, etc. However, the difference is that many of these things are "quality of life" products vs the cool kids club or what's the latest greatest etc.
For people like me, and knife with quick opening and closing is a quality of life issue, as flicking/flipping my knives open and closed helps me deal with my anxiety and adhd issues. Spending the money on a knife with great action is worth it to me, to a point. However, along with that fidget friendliness must come a value in materials used as well. Also, there comes a point where price catches up and it goes from something that is helpful to my issues to being more pure vanity. As incredible as my Brian Tighe small Tighe Rod was, I will not replace it after selling it many years ago, and just can't justify the kind of money.
I am willing to spend the extra money on my mattress etc. I'm 6'4" 250 with spine issues and skull issues, I need the extra support. Same with pillows. I started buying American made shoes from San Antonio Shoe makers out of necessity for special size and support after my second stroke, and in general prefer to support US companies. My mattress, frame, pillows, and sheets are all made in the US as well.
Back to the main point about price. Things have changed greatly over the last 7-8 years in the knife world. $80 won't get you an American made Benchmade mini grip anymore. But that $80 bought you 154cm and grivory, and later on questionable QC. Now, for $80, although made in China, I can buy a Civivi Exarch with CF, 9CR damascus, and impeccable fit and finish. With the increase in knife companies, classically expensive brands like CRK are starting to lose traction IMO as the value per $ goes down. There will always be fanbois of these companies, but lets face it they are no longer the benchmark. Hinderer has kept up with the market in upgrading steel, changing to a bearing pivot, introducing new models, etc. So at least there, your money is still buying you the same thing. However, with the ZT collaborations being excellent, same steel, bearing pivots, its hard for me to justify spending the extra money for the "genuine article" as it seems that its just buying prestige.
As expensive is relative, I've gotten to the point where "mid-tech" knives are more prestige than anything else. Now true custom designs (like my dream knife from Alan Davis) are a different story, where you get to basically input to the maker every specific thing you want in the knife. Alan for example, has a range of designs, you can pick from thumb stud, flipper, front flipper, or two handed, handle material, steel, etc. That is worth $800+ to me. A Shiro etc, not so much.
