Abstract
A pen point for writing with an ink, having a pen nib with two nib points separated by a slit. The surfaces of the nib points perpendicular to the slit have, over a part of their length, a film chemically inert to the ink and wettable thereby, thus forming two lips which substantially cover the slit and abut with one another when the nib is in an unflexed state. The lips extend substantially from the slit origin to the nib tips and consist of a varnish, a plastic material or a metal. The pen point is manufactured by a process wherein a pen nib having two nib points and a slit therebetween is coated with a continuous film of material, chemically inert to the ink and wettable thereby, with the film then being divided to form the two lips.
