I don't do much in a kitchen, if I did I'd have a chef's knife. I'm a weirdo though, so what I do and what I know are best practices frequently don't line up.
To counter your examples though:
Bread? pre-sliced.
Cheese? pre-shredded.
Butter? melt and pour it baby.
So far I didn't need a knife at all.
for the bread and cheese, I'm not a foodie. I'll get medium ish quality stuff at the grocery store, and it exceeds my expectations.
for the butter, come on, its butter. butter is love, butter is life.
