Putter part (5)
I believe the answer is:
shaft
'putter part' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for shaft that I've seen before include "Stem, handle; (light) ray" , "Aggressive remark" , "Ray of light; treat unfairly" , "Body of an arrow" , "Vertical excavation" .)
