Having a knife you just like is the second kind of cool. That is entirely personal to you and up to you to decide if it's worth it. As long as you're not deluding yourself about why you own it, nobody has a right to criticize.
There is nothing wrong with buying something just because you like it. Knives are aesthetic objects, in addition to being occasionally useful. I have several knives I own that just get used for opening packages or whatever because they're close at hand all over my place. You should always have knives around for little stuff like that. But if I'm going and doing something specific, I use the right tool for that job.
It may not be the most efficient way to spend your money, but having a bunch of junk knives scattered about that you enjoy for reasons other than how good the steel is can still be useful and beneficial, and if it makes you happy then go for it, have fun.
It's also fine to own knives purely for decoration. I got some legit war bayonets that I'll never use for anything but I just like owning a piece of history, and collecting things that aren't made anymore.
