A lot of emphasis gets placed upon just how much flex can be derived from a fountain pen these days. Go to any pen show and you will invariably hear attendees asking after pens equipped with flexible nibs. If you frequent any of the popular pen auction/sales sites, a lot of Pelikan’s vintage offerings get put forward as fitting the bill. The principle of caveat emptor should be utilized in those scenarios since applying excessive pressure to a semi-flexible nib can result in great line variation but at the cost of significant stress that could ultimately lead to nib failure. While the company’s nibs from the 1930s through the 60s are excellent and considerably better than today’s offerings, they are not what I would call true flex nibs. It has been my experience that the more accurate descriptor applied to these nibs would be semi-flex with a springiness that imparts a tremendous amount of character to some to these vintage pieces. Of course, there is an exception to that rule. Pelikan produced a nib stamped ‘ST’ which could be found equipped as a specialty nib on various models. First introduced with the 100N in 1938, these nib were particularly elastic and came in EF or EEF. The 140s and 400s had gold versions produced from 1954 – 1965 and the 120s came with stainless steel variants made from 1957 – 1965. These stenographic nibs are truly flexible, putting down a line ranging from EEF/EF to B/BB. It should be pointed out that not all ST nibs are created equal and your mileage may vary. Pelikan also made specific pens dedicated to stenography in the 1970s and 80s which should be held apart from the nibs discussed here. Those models comprise the P11, P16, and P470 lines which are all nice writers but the nibs are certainly not what I would call flexible. I can only surmise that the differences might owe to the various stenographic systems that have been used over the years. Pitman relies on line variation where Gregg and Teeline do not. Read on to learn about how these flexible nibs were meant to be employed.
