Let me show you some Ken Onion hand made customs that were recently stolen from his luggage. Estimated value around $20,000.
I think he's a good craftsman. Not my taste in knives, but he can sure make a pretty knife.
William Henry also makes some high end Kitchen Knives with a ZDP-189 Core and laminated damascus. I like this better. They cost more than the Shun. This set has an MSRP of $2950.
I think these are stunning.
Using an expensive knife can be a sheer joy in appreciating the beauty, the craftsmanship, high quality materials and it's excellent edge and edge-holding.
If those issues don't matter to you, then it's a waste of money and knife. If it does matter to you, it makes a big difference in your use and enjoyment.
