Pointed end (3)
I believe the answer is:
nib
'pointed end' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nib that I've seen before include "Pen's point" , "Writing point of old pen" , "Writing tip of old pen" , "Part of a fountain pen" , "Point of an old-fashioned pen" .)
