Florence, Italy
Inspired by the Leonardesque knots also known as “vinciani knots,” Luigi Trenti’s new Filum Pen for Pininfarina Segno is the first product of its kind made completely through “direct metal laser sintering,” which consists in fusing Titanium powder by means of a powerful carbon dioxide laser.
The Filium Pen won a recent 2021 Good Design Award from The Chicago Athenaeum: Museum of Architecture and Design and The European Centre for Architecture Art Design and Urban Studies.
For this writing instrument, complex circular geometrical interlacing weaving creates this masterpiece—the result of the highest level of construction engineering.
Leonardo’s knots were inspired by the use of flexible twigs of red willows trees—typical of the town of origin of the artist and scientist—to weave baskets or tie the vines.
These weaves then became a sort of signature, a personal emblem that he used everywhere in his jewelry designs, hairstyles, accessories, and in the decoration of the Hall of the Axes in the Castello Sforzesco in Milano.
