But if in the history of the fountain pen the clip has distinguished itself mainly as a stylistic element, it has also played a not insignificant role on the technical level, starting from the various methods of assembling it (such as the washer mounting), or the measures to facilitate its introduction in the pocket (the Roller Clip of the Eversharp), to block the screwing of the cap (the Lox-Top of the Chilton) or to block the clip on the jacket (the hook clip of the Novum).
