One of the main characteristics of Porsche Design writing instruments is their mastery of the interplay between materials, technology and function.
An outstanding example of that is seen in the propelling pencil in the P'3130 series. the barrel consists of 17 gleaming stainless steel stems. The unusual feature is the mechanism. As the point extends or retracts, the stems twist and lie straight, then again form a 'waist' in the middle as the end position is reached-a fascinating process. Design and function in one.
Further intelligent details confirm the innovative technology: the clip can be removed or replaced by rotating it a quarter turn. Even without it, the pencil will not roll off the desk.
The fittings are platinum coated solid metal. The pencil has tough 0.7 mm leads of grade B.
