Can a one-dimensional blade cut everything ? (chainsaw) (Sword)

I was thinking in a character who has a...kind of Steam powered Chainsaw, and a sword, what make them special is because the blades of the chainsaw are one-dimensional, same with the sword, they are made of iron.

I was actually curious what could they cut and what not, or anything with that level of edge can cut everything ? and, if that is the case, Could a one-dimensional paper cut with "ease" a Steel spoon ? Or my Iron Chainsaw could cut a armor made of Nuclear pasta ? ((just assuming that somehow someone manage to "deactivate" the gravity that thing should apply over everything, also assuming that material is solid, this is just a crazy totally hypothetical scenario, i actually don't want that kind of armor in my story))

Or be one-dimensional actually would made these thing very fragile ? if that is the case, just the edge part is one-dimensional (With one dimensional i am referring to something with thickness of one atom, only less if is scientifically possible) I would really appreciate it if someone clarify my doubts, thank you
