ELi5 How do sharp objects cut flesh? More in body

Question

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?

On a side note. Some surgical needles are taper point. They don’t actually cut anything. They just push through tissue
