I'm not going to answer anything, unless its telling me exactaly what the problem is, because, I see no problems anywhere. (Accept on the cleaver, a tiny bit, but that will be finished up in my final polishing, which is very quick)
Frying Pan:
The handle. By looking at it you can tell it is adding a load to the polycount. I assume you found that shape in "Extended Primitives" options, but that is irrelevant.
You could/should make a better handle with a simple cylinder (1 stack, maybe 6-8 slices), extrude the ends and then scale down to make a handle.
Lastly, those two gray button-things inside the pan, they have the same problem.
And again you could fix it by using a cylinder with one end extruded and scaled.
Other then that, it is fine.
Spatula:
You need to reduce the amount of slices used on the whole thing. It shows many polygons for what could be a simple low amount by using less.
The inside-head part is fine.
Overall, it needs a re-model with less faces/polygons/slices.
Butcher Knife:
Overall, it is fine.
Those gray button-things on the handle need the same treatment as above.
Pot:
Same as Frying Pan. Handle and gray buttons.
