That Horimoto looks fantastic. I may have to arrange for something unfortunate to happen to either my Henckels or Global chef's knife.
Would you be opposed to a high carbon steel? If not, I can't recommend the Hiromoto 240mm enough: http://www.chefknivestogo.com/higykn24.html
Don't be like me and become so paranoid of the "high maintenance" that you're afraid to use it. For the past several months, it's practically all I use except when it comes to heavier duty tasks.
Stop by a Williams Sonoma or other high end kitchen store. Handle some knives. You don't have to buy there, but you really need to get a feel for the different styles. Some prefer a German shaped Chef's knife, some a French style, some a Japanese.
It's especially important with a first purchase to get what will hopefully become your workhorse into your hand first to see how it feels. Demo some 8" and 10" knives in the different styles to see what suits you. Once you get a feel for which shape and handle type you like I'm sure we can help you find some great options.
Haha, I didn't see guerreit's post. What he said.
I'd go with the knife found in many commercial kitchens: The Dexter Russell Sani Safe. The will hold an edge as long as a Forschner and they have very comfortable handles. Dishwasher safe. Less than $30 at most chef's supply stores.
buy your________ based on photographs and recommendations from the internet.
Silliest/foolish thing I've seen on B&B.
