SieMatic S2 From the inventors of the handle-free kitchen. In 1960, SieMatic presents the first handle-free kitchen to the world. Since then they have constantly reinvented the design. The handle-free SieMatic S2 is again a sign of perfection of design, workmanship and function. In a time when many things are alike, it offers purist kitchen design something of special value: character and personality. These characteristics come from the many high-quality and comfortable features that were developed exclusively for the SieMatic S2.
