The difference between practical knives and art knives is like comparing a canvas tarp to the Mona Lisa. They are two different products intended for very different audiences. Obviously there is some middle ground, which depends laregly on the depth of the customer's wallet. If someone wants to use a $10K knife to chop wood then power to them. But, for the most part you cannot use the same yardstick to measure these knives.
There is no good, no evil, no saints, no demons; There are just ordinary people making ordinary choices.
