Press for a golf club (4)
I believe the answer is:
iron
I believe this clue is a double definition.
'press' is the first definition.
(I know that press can be written as iron)
'for a golf club' is the second definition.
(type of golf club)
(Other definitions for iron that I've seen before include "Metal obtained from haematite" , "Press clothes" , "Former dividing line across Europe" , "Main part of steel" , "Flatten; element" .)
