Needle feature (3)
I believe the answer is:
eye
'needle feature' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eye that I've seen before include "Needle or lace hole" , "Aim for" , "Storm-centre" , "'Cast a cold ... on life, on death' (Yeats)" , "See 1" .)
