I found an interesting knife website.
http://zknives.com/knives/index.shtml
A lot of information on different knife steels.
http://zknives.com/knives/articles/knifesteelfaq.shtml Sharpening.
http://zknives.com/knives/sharpening/index.shtml And reviews of different kitchen knives, mostly Japanese.
http://zknives.com/knives/kitchen/index.shtml
Now, the guy is clearly a Japanese knife bigot, but even so I thought this info was worth reading. I wish I had a bunch of $600 hand-made Japanese kitchen knives to test.
I noticed his comments on Shun knives. His comments are lukewarm, but that is in comparison to some fairly rarified (in the US anyway) hand-made Japanese knives. Looks like he considers them better than practically anything else you can get at Sur La Table etc.
Edit: oops, I see this site has already been posted by myamoto. Sorry.
