Helping with needle (3)
I believe the answer is:
pin
'needle' is the definition.
(both can mean a sharp point)
'helping with' is the wordplay.
'with' indicates the answer is hidden within the clue.
'PIN' is hidden in the letters of 'helping'.
(Other definitions for pin that I've seen before include "Fastener; skittle" , "Fixing device" , "Flagged stick placed in golf hole" , "Fastener; brooch" , "Number allocated for electronic transactions" .)
