The design reasonning of Stilo handle was based on the revision of the processing technique. Specifically, Enzo Mari- father of this handle, decided to change a phase in Stilo’s process. His alternative is machine-turned brass for the level. Stilo utilizes turning as a more elementary substitute for the traditional techniques of moulding or casting. This method is appropriated to the cylindrical rod of the lever as well as the shaft, the latter of which was designed with a shape that can match well with all kinds of variants.
