I've become a fan of buying knives at the restaurant supply store. Better grips, nice sharp blades, and cheap. Downside is they look like they belong in a restaurant kitchen instead of a showroom. But hey, they work great.
I have some santokus and personally don't prefer them. Give me a heavy chef's knife any day as a go-to blade. For BBQ, I've bought specialty stuff--a 10" scimitar and 6" boning knife for general carving of raw meats, a 4" utility for close-in work on pockets of fat, and a 12" granton edge slicer for slicing briskets. Turns out the tools that butchers use really are the right tools for the job when it comes to cutting big hunks of meat.
