I disagree. It's not that people aren't "smart enough to find a forum like this". When I started looking at knives, I was considering a Shun because there are many, many reviews out there by people who really like them. I asked someone who was a professional cook which were the best knives, and he recommended a Shun. Who knows--I might have bought one and been perfectly happy with it. (And my wallet would be much thicker!) Shuns are probably much, MUCH better knives that what you see in most home kitchens. Are the they best knives for the price? Many on this forum tend to think not. But they are readily available from well known vendors, and if you check reviews from vendors like Amazon, most people are really happy with them. Add celebrity chef endorsements (and you KNOW celebrities would never lie to us!) and there's a comfort level in buying a knife that is widely known and generally well liked and getting it from a big-name store who can be relied on to stand behind their product. Going from a $39 knife set to a knife that costs $100 or more is a big step for many people, and it's easy & convenient to just buy the same thing that hundreds of people love rather than trying to dig deeper.
Most people don't give a rat's behind what a choil or distal taper is, they just want something that will chop their carrots.
