No, there is some truth in that it's helpful to have owned many other knives to help you figure out if what a CRK offers for the money is worth it to you. I think some people just try to take offense to that statement for some reason. I sure as hell know after owning CRKs whether I think Hinderers and Striders are worth the same amount.
I've been fortunate enough to have owned many different folders from various top companies and have gotten to really experience and take notice of what I personally find value in with a folding knife. I'm pondering selling possibly 1 or 2 CRKs and a Hinderer because they're essentially becoming expensive paperweights. Precision engineering and overbuiltness although nice don't necessarily equal value to me. Especially when the $400 knife does its job (to cut) worse than a $60 knife (sharpened pry bar reference). You shouldn't have to force yourself to like something just because you paid $400 for it. You should know relatively soon if it hits all the right notes for you. If it doesn't then there's nothing wrong with that.
For example, I had to get an Umnumzaan because I briefly had one I had to return due to lack of disclosure, and in the following 9 months, found myself staring at pictures of them till I obsessed, sold something to fund it, and bought a new one. It's basically sat in the safe since with maybe a bi-monthly fondle. It's cool and it's nice no doubt, but I'm having trouble finding the value in it for me. It's heavy, less easy to open and close than the Sebenza, not as comfortable in hand as a large 21, and the blade shape discourages me from carrying it. So why do I still have it? I'm not a collector and prefer a minimalist approach. Some are ok with having thousands of dollars in knives sitting around being unused, and although I can currently afford to keep it and all the others, I have a certain amount of guilt not carrying and using it.
I used to have a limit of $150 before I got into high end folders. I couldn't fathom paying more than that for a knife. I soared into the realm of $400 shortly thereafter and figured that's where I'd stay. But naturally our tastes evolve and change through experience. I really like my Sebenzas and carry them a lot, but the knives I really have fun with and enjoy using are my Spydercos. Guilt free, worry free knives that feel great, are easy to manipulate, and do their job better than most any other. So lately, through experience, I find myself trending full circle back towards that $150 and below mark knowing there's a ton of value there (to me). This is not a knock at CRK as they're in a league of their own, but what we personally like and find value in are our own decisions, and we shouldn't have to justify it to anyone else.
