That would be one end of the spectrum, there are some folks that collect others that just use their knives. Nt all are the same.
I used to be into collecting custom hunting knives, with no intention of ever using them. I don't really need a hunting knife to use but I did pick out one that I thought I could use if I ever needed one.
But OTOH all of the folding knives I buy are intended to be used, and I do carry them.
The most I have spent on a knife for carry is a used ZT0561, but I prefer buying EDC knives for less than $150.
