The last model of historical significance is probably the [[Hastil]], designed by the famous architect [http://it.wikipedia.org/wiki/Marco_Zanuso Marco Zanuso] and launched in 1970. It realized an huge international success, so that a copy of this pen is permanently exhibited at the Museum of Modern Art of New York. Made with a thin cylindrical steel body, the pen is characterised by an advanced feeder (called ''[[Idrograph]]''), by a nib mounted in a central position and by a cap with a peculiar retractable clip that falls within the cap when at rest, but that can be open when the pen must be inserted into a pocket.
