Featuring a minimalist design that Müller had developed by following strictly functionalist criteria, the LAMY 2000 signalled a conscious break from the classic and traditional style of pens that dominated the market in the 1960s. It came to define an aesthetic of restraint, which still to this day informs the design of all Lamy products. As a trained carpenter whose skills were honed while working at Braun, Müller was immediately able to contribute his own unique style of work. Rather than design sketches, he preferred wood and plaster models, which he himself made and displayed at the Lamy factory. The LAMY 2000 was no exception: the initial design already closely predicted the form the product would eventually take, although little attention was at this stage paid to its technical feasibility.
