Usually the tip of the nib is made melting directly on place a ball of iridium (or equivalent material), and then it is cut in two dividing the tip in the two tines for the realization of the slit through which the ink coming from the feeder must pass, and then suitably polished to offer a better smoothness. In general then, both to allow the air to escape from the conductor and to reinforce the end of the slit, the nib is equipped with the so-called "air hole", even if in many cases the only purpose for it is to give a better mechanical strength and flexibility. Some nibs also, such as the Triumph Nib of the Sheaffer, or the central nib of the Omas 361, are specially designed and machined to write from both sides, including therefore also the so-called dry side.
