A weak topological insulator (WTI) bears, generally, an even number of Diraccones on its surface; they are susceptible of doubling, while on the surface ofa certain orientation it shows no Dirac cone. On this "dark" surface of a WTI,we predict the existence of a single pair of isolated 1D perfectly conductingchannels that forms either a closed loop or a segment of a line. The former isassociated typically with a single atomic-layer-thick island formed on the darksurface, while the latter is shown to be the consequence of a pair of crystal(screw) dislocations terminating on the dark surface.
