Pens and pen nibs are used throughout Navy drafting shops. The proper care
and correct use can prolong the life of a pen nib. Pen nibs are made by many

the stroke, or they maybe irregularly shaped to produce a line of unequal
width depending on the direction of the stroke. There are pen nibs used

nib, moisten it slightly to remove the manufacturers protective oil. To fill a
pen nib, supply ink by dropper or brush to extend 3/16 inch up the nib blade.
