I am only talk about folding knives here.
I was about to post something related to this thread. I am very surprised to see knives are being treated like a designer handbag for women, Rolex watches type of STATUS item rather than a TOOL. Never have I even dream about like this before I join knife forums and read and find out the price of some of the knives.
I am NOT advocate in buying cheap knives, but to me, at $45 to $90 range, you can really get good knives. I am not even saying the cheaper ones are all bad. Case in point, I bought a S&W on sale on Amazon for $9.95 a month ago.

I actually did testing on blade hardness by hitting the spines of two knives against each other to compare who make a bigger scar. This $9.95 knife fair VERY WELL against more expensive brands(cheap in a lot of people's eyes here) like Kurbey, Steel Will etc. in $60 range.
I understand the comparison between a Kia car to Mercedes, that the Kia might be more reliable than Mercedes. BUT, the big difference between knives and other luxury items is People show off with designer handbags, Rolex watches by wearing it out in the open, it is like jewelries. You do NOT carry a knife out in open, you mostly conceal it. Even if it is legal, if you carry openly, 95% of the people will look at you strange rather than with admiration how expensive the knife is!! Hell, it's NOT that expensive even at $700!!!
To me, a knife is a TOOL, nothing more than a drill driver or circular saw that you do NOT carry openly to show off. I understand a high quality knife can cost like $100. BUT over $500 a knife? What can a $500 knife better in any way than a good $100 knife? What kind of steel use in the blade that make it so expensive?
Heat treat is NOT rocket science, I am sure people can automate the process to get as good a heat treat as any human can do. It's just programming the machine. Knife is such a LOW TECH item there's no secret about it, it's really really simple.
So why are people so into expensive knives? For me, I would not pay more than $100 for any folding knives. I bought close to 20 knives between $20 to $80. I do notice how bad some designs are. My conclusion is I have to buy it, open it to tell, test the blade hardness, not just read what kind of steel they advertise using. My most favorite knife under 3" is a CHEAP JSWS knife that was $16 when Amazon had 40% off. I look at the design, the hardness of the steel in real test. My favorite bigger knives are all Steel Will with Phosphorous Bronze washers all in $70 range. I would have gone to Cold Steel if they have flipper tap rather than thumb tap. Steel Will is about the only other one I like with PB washer.
Also I get into knives for self defense, I practice knife fight, striking on hanging heavy bags with rubber knife. There is a purpose for me. How many people actually use knife they carry other than open letters or boxes that you can do with a cheap box cutter? I do NOT use even my cheap knives to do that to preserve the edge. I use box cutter.
Important to note, I am NOT against spending a lot of money on items to show off. I am willing to buy Rolex watches, nice cars. I just cannot see spending money for a knife that I cannot show. $700 is nothing, but it's just not worth spending on a knife. Find something that can show better and spend more money.
