Part of a golf club (5)
I believe the answer is:
shaft
'part of a golf club' 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 "Vertical passageway, into a mine say" , "Stem, handle; (light) ray" , "An arrow or a mine passage" , "Ray (of sunlight)" , "Beam - well" .)
