Pomelllo was actually a knob. It has a better life now: it has become a tool for smoothing stone. This tool was born from the need to use a manual tool to sand without spreading too much dust. Pomello prefers slow work, gives sense to time, avoids vehement and muscular actions. The geometry is simple, modeled to welcome the touch and grip. Don't worry, you can easily find abrasive discs in hardware stores.
