Other solutions were produced for the same type of problem, such as the creation of appropriate side pockets next to the channel (as in the Spoon feed of Waterman). Over the years, the development of mechanisms has continued, either with the presence of engravings in more or less jagged shapes of the external part (as in the Spear-head' of Parker), or with the realization of fins, bags, engravings, channels and other configurations, to allow any excess ink to accumulate properly in the various folds, and avoid dangerous accumulations on the nib, in particular to compensate for pressure changes due to air in the tank, a problem that has become even more significant with the emergence of air travel.
