Filling Instructions: Piston-Fillers |
|
The standard filling mechanism for better European-made pens since the later 1930s, piston-fillers utilize a screw mechanism to move a piston inside the barrel, taking in and expelling ink. The mechanism is typically actuated by turning a knob at the end of the barrel, although in some instances the turning knob is concealed underneath a blind cap. While some piston-fillers incorporate a tip-dip feature, in most cases the nib must be fully immersed when filling, just as with other pens. Montblanc piston-fillers made up until the early 1960s used a two-stage screw mechanism. Very little resistance is felt for the first few turns, which sometimes fools the uninitiated into concluding the pen is broken. |
