Post Office produced locksmith’s tool? (6)
I believe the answer is:
pomade
'locksmith's tool?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'post office produced' is the wordplay.
'post office' becomes 'po'.
'produced' becomes 'made' ('make' can be a synonym of 'produce').
'po'+'made'='POMADE'
Can you help me to learn more?
(Other definitions for pomade that I've seen before include "Scented hair dressing" , "Scented ointment for the scalp" , "Oily dressing for hair" , "capital application" , "Perfumed hair oil" .)
