In the last years sensitive probes of the carrier-envelope-phase offset of few-cycle laser pulses have been discovered and developed into high accuracy phase meters. They are based on the re-scattering process of photo-electrons at noble gases like Xe  and at nanoscale metal tips . We report on a comparison of the CEP dependence of these two systems which yields insight into the nano-optical response of the tip with attosecond resolution. Further, the nanotip allows for making a quantitative measurement of the behaviour of the carrier-envelope-phase of focused few-cycle laser pulses. These effects are of high interest in the field of nano-optics, plasmonics, attosecond-pulse generation and ultrafast science in general.
