I think there’s something to be said about the tangible and acoustic qualities of a folding knife, sound, feel in hand, visual design, etc, and undoubtedly, the combination of those things that jazzes one up can be different for everyone, hence the market. I wouldn’t necessarily always equate to quality and/or durability, as I’ve had some cheapies over the years that were super satisfying to open or close for one reason or another.
In guns for example, aside from the joyful sound and smell of burning gunpowder, who doesn’t love the action of a nice autopistol slide where the balance between slick action and tight fit has been well-executed, the clocking of a well-timed wheelgun’s works, the dropping of a bolt carrier group, or something as simple, yet iconic as the “ping” of an expended Garand clip? The sensory experience is part of the enjoyment.
As for the reviewing community buzzwords, yeah, that gets annoying.
