I can tell you. It is like people who buy cars.
Some people only want a car that gets from point a to point b reliably. Most people, however, want to show off.
I have two different Kershaw models. One is discontinued. It was actually discontinued, as I understand it, because of a design flaw. The second Kershaw model has the same blade length, functions the same. I didn't know of the second Kershaw model when I bought multiples of the first model. Maybe the second model was not even being produced, I don't know. The first model now sells for close to $200. I was buying the second model last year for about $22 delivered.
I have a pile of Ek knives somewhere. When the manufacturer went out of business (sold the name and design rights), I sold off some because I had no use for some and didn't like a couple of designs. The successor uses a different steel. People want "the original" and pay through the nose.
I drive a 16 year old car that functions perfectly. It is a Toyota Avalon. I live in a neighborhood wherein people only buy new and the car has to be a BMW, a Land Rover, a Jaguar or a Tesla. (My neighborhood was constructed as tract houses for aircraft workers and now has 90% McMansions). My car will still be on the road when the others (gee! Look, I can afford a BMW!!!) have gone to scrapyard. Same thing.
