The optional medium-duty Rocker head is a QuikSwap tool for the Evolution3. It is a general-purpose cutter for materials such as banners, cardboard and foamboard up to 10mm (3/8″). The ergonomic design follows the natural curvature of your hand and offers maximum comfort for everyday cutting. It also provides two-way cutting – pulling to cut lighter weight materials and pushing for those that require more effort. For those who occasionally cut aluminium composite panels, such as Dibond or Alupanel, the Rocker head can be fitted with the Tech-D.012 blade. The cutting technique requires a series of careful strokes and we advise that you watch our video guide to perfect your cutting action.
