I think many of us get so caught up in all of the stuff that we read about on these forums and lose track of the fact that our opinions are just that. People who forget that they're stating personal preferences might tend to judge others about their preferences. We certainly can make objective, factual statements about knives, but in my experience most of the questions that come 'round these parts are attempting to gauge (a highly subjective) consensus to better equip their own decision making in hopes that they'll be able to find a knife that meets their own highly subjective preferences. Preferences, mind you, that the relative newbies don't even know they have just yet in most cases.
When I first got here, I "needed" the fastest, most tactical knife in the world- under $80, lol. I hope I don't scare anyone off from asking these questions however, because they really do help us find out what we really like about knives. Reading feedback about various knife models does help in many cases. What we'll also find is that we'll personally go through many knives, buying, trading and selling and that will change much of what we prefer over time. Some unfortunate souls get caught up buying, trading and selling almost for the thrill of getting the "latest and greatest" and have the most difficult time determining what features they really like. Okay, too much typing now, I'll shut up.
