So, we’re all made out of cells, right? And these cells are really super tiny, so why is it when we accidently cut ourselves, like a papercut or from glass, the sharp edge just doesn’t push the cells to the side?
Further, do those edges push aside out individual atoms too, or somehow have we just been avoiding death via splitting atoms?

The main reason it doesn’t push cells to the side is that cells themselves are bound together to other cells by these things called “ligand” proteins. Ligand means “binding”.
Think of it kind of like tying the sides of boxes together from the inside with zip ties.
The other main reason is the cells aren’t rhe only thing there. Most of our tissues are made of things cells MAKE as well as cells, primarily proteins, and things like bone which are proteins plus minerals, things like skin which have living cells in the underlayment but layers of toughened dead cells on top, etc.
So the blade may or may not cut actual cells, but will cut tissues, made of proteins.
