I've seen single present day Japanese knives go for over $1,000. The knives used in sushi bars probably START at $400.
I have a set of Japanese knives, made by a now deceased master, that were bought in the early '70s. I consider them to be priceless, even though I know my mother paid little (in today's dollars) for them. I think in those days, a dollar bought over 400 yen. I heard that a single blade, no handle, by this master went for $1,500 about 10 years ago.
Yes, these are all damascus blades. You can see Mt. Fuji in these particular knives.
