And that's a good enough reason IMO. Part of living in a free society means not having to justify every little thing you do. I'm a college student, I don't need a pocket knife very often, except for small things like opening packages and boxes etc. There are some days when I don't use a knife at all, and the majority of days I could probably get by with just a little keychain sized SAK. But I like carrying a larger one hand opening folder, so I do.Point being: there is absolutely no reason, other than desire, to have as many knives as I have/know as much about them as I do
