Club used in the evening (4)
I believe the answer is:
iron
I believe this clue is a double definition.
'club' is the first definition.
(type of golf club)
'used in the evening' is the second definition.
(I've seen this before)
(Other definitions for iron that I've seen before include "inflexible > club" , "rations in emergency?" , "Press - element" , "Strong metal; golf club" , "Smooth - driver?" .)
