Funny thing this article doesn't really talk about REALLY expensive knives. Just "Mall Fancy" (gatekeeper's delight: if you can buy it in a mall, it's not 'real' bling.) There's a custom knife store I visited in Portland last year that goes up to $3k for handmade knives.
Expensive knives are silly. $49 Victorinox is probably one of the best knives out there unless you're a sushi chef according to just about every review. I have one, it's great. Better than my Shyun for the price and easier to put on edge on.
But don't take my anecdote for it: go talk to a chef and ask what kind of knives they use. Know what the answer will be? In most restaurants they are from Sysco. Source: friends that work back of the house.
