If I cut a thing in two, are the two pieces together exactly the same size as the original?
Or to rephrase it: does a knife/scissors/etc just split something or does it remove something?

It will remove some amount of material when you cut.
If it is enough for anyone to care about is another question.
Or was the question what happens on a molecular level and if cutting is any different than sawing at that level?
