I used to think that their were simply two types of knife owners: Users and Collectors.
I am inclined to believe that are actually three types: Users | Collectors | Social Media Connoisseurs (for lack of a better term)
Users are folks who, despite being knife enthusiasts, still want a knife in the pocket to use for whatever needs that might come up. They treat their knives as tools and typically are more concerned with function and cutting abilities versus its aesthetic properties.
Collectors are folks who are not as concerned with function and/or cutting edge, but they do care about aesthetics, do not want blemishes, and treat their knives as more of an investment. I am putting this in simple terms for the sake of the conversation but the mind and desires of a collector can be rather nuanced and I do not want to disparage that in any way, shape, or form.
Social Media Connoisseurs are a weird hybrid of sorts and I think they reflect a bit of the "crossover" that Mike mentioned earlier. They typically go through a rather high volume of knives, they buy and sell A LOT. They care about aesthetics (first and foremost), construction materials are a very close second, and though they may never use the knife, they care a lot about its function and edge. Virtually every aspect of the knife is combed over, inspected, and judged accordingly. This gives birth to YouTube reviews, pretty Instagram pictures, Reddit discussions, and the like. There is nothing inherently wrong with this as I do believe this gives rise to a heightened enthusiasm and bolsters the knife industry significantly, as Mike has mentioned as well.
I am likely an amalgamation of all three. I use my knives, knowing that they are tools, but I like collecting and there are knives in my collection that I will likely never get around to using all that much. I also care about construction materials, I am mildly concerned with centering, good fit and finish, etc. and I appreciate excellent photography and well written posts.
On the flip side, I do not use my knives particularly hard (unless it is a stout fixed blade), my collection, though burgeoning, is not comprised of strictly mint knives, and I do not go through a large volume of knives and I keep my expectations reasonable.
I guess the point being: There is room in the knife hobby for all sorts of enthusiasts and though some of the complaints can become tiresome, they do contribute to an overall balance that can serve to keep us grounded.
