Finally, being an essential element of the fountain pen, the nib has undergone some constructive variations by companies. Initially there was a differentiation carried out mainly in the construction materials of the body and the tip, but until the '30s has always remained virtually identical in form and function. The first significant diversification was the one introduced by Eversharp in 1932, with the variable flexibility nib called "Adjustable Point" equipped with a slider. But the most significant changes began in 1941, with the market release of the Parker 51, which marked the debut of the hooded nib. From then on there were evolutions such as the conical nib of the Triumph, the various versions of the winged nib from Wing-flow onwards, or the particular "inlaid nib'" introduced with the PFM.
