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?

If you shear (scissors) then there should be less loss, maybe some distortion though. If you saw, you lose the sawdust. if you slice (knife), it might be either way or a bit of both.
Most likely you lose something, whether it’s a loss that matters, that depends.
