We have some Shun classics that we have used for about 9 years with no issues. We have them hand sharpened every few months for a whopping $5 each by a pro shop and they are in nearly new condition. We use them daily and they are great. They have even survived the dishwasher a few times when guests were over for dinner and they thought they were "helping" by cleaning up afterwards and putting them in the dishwasher without us knowing until later. :/

I would imagine that a professional sushi chef might scoff at them, but I'm not a pro chef so why do I need to spend several thousand dollars for a set of knives?
