A wedge on a surface singularity (S, P) is a formal parametrization of S by power series in two variables, locally at P. A genericity condition, which is expected to be enough to guarantee that a wedge lifts to the minimal desingularization of the surface, is proved to be so if the singularity is sandwiched.
