The reversible rearrangement of weak metal‒metal bonds in layered transition metal chalcogenides is shown to be induced by the force exerted by the tip of an atomic force microscope. The figure shows how the ribbon chains which make up the layers of NbTe 2 are reversibly switched by 60° by increasing ad decreasing the force at the tip.
