As someone coming back to the hobby in recent years, all I can say is that i am very dismayed by the inflation that I've seen, especially in the past few months. I really will not pay more than I think a knife is worth. I'm not sure how much markup there is, but I am sure that a lot of you have been overpaying for quite a long time and have been conditioned to simply accept it. Don't take that as an insult. This isn't me preaching about how others should spend their money, but a statement about how reluctant I am to squander mine (I buy dumb things, too). I do also recognize that the costs to make a knife have gone up, but the most noticeable price increases started before the pandemic. At least, that's when I started noticing.
I haven't even thought about resale value for myself. If times got hard, there are far more instantly sellable items in my possession to part with before I get to the cutlery. I doubt I would break even on any of them, and besides that, they are far more useful in a practical sense than most of the other stuff.
