Pelikan is a company with a longstanding reputation for solid engineering and conservative design. This conservatism was particularly in evidence in the Pelikans of the 1950s, with one notable exception: the Pelikan 60 mechanical pencil, also known as the "Knickebein", meaning "bent leg". Neither twist nor button-activated, this pencil bends in the middle to advance the lead, as shown in the video clip below.
