I have several brands of good knives, and find little difference. I find that just keeping my knives sharp is more important than brands. I have a Chef's Choice sharpener that i use once or twice a year, and a Wustoff honer that I use with almost every use. The honer does the same thing as a "steel" does.
I posted this link in another thread knife sharpening, but it fits here, too.
Here is a link to a good video. The professional knife sharpener in this video says that the most important thing in a knife is that it feel good in your hands, because the knife you like to use is the one you WILL use.
In his show, Good Eats, Alton Brown says we shouldn't sharpen our own knives, that we should send them to a pro. Well, I like to do my own anyway, even though I'm sure a pro would do it better than I do.
The good thing about this video is that he shows a pro working on his knives, so we can see what he does.
He also does a good job of explaining the difference between sharpening and honing, and show the proper use of a "steel" to hone knives.
