Sewing tool (6)
I believe the answer is:
needle
'sewing tool' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for needle that I've seen before include "Annoy by constant criticism" , "Sewer's implement" , "Sewing implement used to annoy" , "Informal name for hypodermic syringe" , "Sharp instrument" .)
