I'll tell you the truth from my point of view, No BS...
I use Global knives at home, these are quite expensive, my chef's knife was £180.
When I started BBQ, I bought some cheapo knives for doing BBQ as I din't want to take my globals to competitions. These knives lasted me a few weeks before i got thoroughly p155ed off with them. I ended up buying some Friedr Dick butchery knives. These are just poly handled jobs, not pretty and not too expensive, but they are stunning to use.
Henckels do a similar range, they're knives for pro's rather than being designed to look good in your kitchen. But they have been a fantastic investment, they make prep so much more pleasurable and allow me to work quickly without cutting myself. Much like my Globals do when I'm in the kitchen. The key thing is to keep them sharp.
I use a Dick serrated slicer for slicing brisket and cutting ribs. Never thought I'd like a serrated blade but my slicer is a beauty.
