I have several Classics. I like the look and the utilitarian value of them, in a very small and pocket friendly package.
That said, that's not what I usually carry on a daily basis. If I'm carrying a Classic, it's most likely because 1. I'm going to be somewhere that limits the blade length of what I can legally carry 2. I'm going to be in a situation where my clothing or activities will make carrying something larger/heavier inconvenient 3. for variety, just because I like to carry different things on different days, depending on what I expect to be doing.
I won't be trying to psychoanalyze why people prefer to carry tiny knives, or big Bowie knives, or any other kind of knife - or no knife at all. I'm just going to give the benefit of the doubt and assume that it is just that: personal preference.
