Design and ergonomics
The Pininfarina Segno Speedform pen develops a perforated pattern along its entire length, which reaches its peak in the central area.
The perforation is designed specifically to enhance the Ethergraf® technology, which does not require cartridges or refills inside the stylus.
The tip starts with a circular section and twists into a blunt triangle, which outlines three twists; then it tightens again into a circle at the tail.
Ethergraf, the stylus that writes without ink
The ETHERGRAF® tip microscopically "scratches" the paper, oxidizing it and leaving a light but indelible mark.
Thanks to its porosity, ordinary paper, i.e. untreated cellulose paper (made from plant fibres bonded together through a process called "felting"), is a material that reacts perfectly to the passage of the metal tip.
Integrated pen rest
There's a secret to the Speedform pen: a small magnet located near the tip.
This allows the pen to remain balanced on its base, defying gravity and increasing the perception of dynamism.
The Pininfarina Speedform pen is made of 3D-printed aluminum, making it extremely lightweight; the progressive perforation, then, balances the product's ergonomics, adding a fascinating play of light and shadow.
