Picos

The tapered or beveled tips or pairs of blades that form the pen point of a reed pen, quill pen, or pen with a metal point, such as a fountain pen. The term may also refer to the removable metal pen point of a pen, as distinguished from the handle or holder of the point. It may also refer to the tiny ball of iridium on the tip of a metal pen point, as distinguished from similar pen points that are blunt or have a fine sharp point. Nib is also used to refer to one of the two blades that form the point of a split pen point.
