Slicing metal to the thickness of a single atom is not feasible with traditional blades, as no blade exists for such precision. However, depositing a monolayer of atoms is achievable using techniques like scanning tunneling microscopy (STM). These methods allow for the manipulation of individual atoms, making atomic-scale construction possible. While theoretically, with enough time and persistence, one could attempt to achieve atomic slicing, it remains impractical with current technology. The discussion emphasizes the distinction between slicing and depositing at the atomic level.
