I see knives all the time since I work mostly on construction sites, but they're usually junkers. Weirdly enough, they're usually Kershaw Leek knock-offs. Of the very few people I've spoken to about it, one guy actually knew what the original Kershaw model was; when I asked him if it was a Leek, he showed it to me and explained in a semi-embarrassed tone that it was indeed a fake. He also pointed out how poorly it opened. I don't remember if it was spring assisted (like the original) or not, but I remember it opening slow and ugly.
At my other job, which is retail, I was very surprised to find there are at least two self-professed knife collectors. Their top-shelf knives are current CRKTs and Gerbers. I showed a couple Spydercos and Benchmades to them both and while they were pleased, a bit of chatting revealed that they don't really know much about knives beyond what they can glean from shopping at Walmart and sporting goods stores. I tried to engage them both in some fairly nerdy knife talk and it was like I was speaking moon language. But hey, a knife enthusiast is a knife enthusiast -- I don't care what you know own, as long as you support the industry and you're into blades!
