Clubs with metal heads (5)
I believe the answer is:
irons
'clubs with metal heads' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for irons that I've seen before include "for old convict to wear" , "Smooths the golfclubs?" , "Smooths, presses" , "Jeremy ---, Br. actor; golf clubs" , "Golf-clubs with metal heads" .)
