A writer's point (3)

I believe the answer is:

nib

I believe this clue is a double definition.

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

'point' is the second definition.
(I know that nib is a type of point)

(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.
