A writer's point (3)

I believe the answer is:

nib

I believe this is a double definition.

'a writer's' is the first definition.
(something which writes)

'point' is the second definition.
(I've seen this in another clue)

(Other definitions for nib that I've seen before include "Part of a fountain pen" , "writer" , "Point of an old-fashioned pen" , "Writing point of old pen" , "Pen's point" .)

I've seen this clue in the Evening Standard.
