Fetters; smooths (5)
I believe the answer is:
irons
I believe this is a double definition.
'fetters' is the first definition.
(I've seen this in another clue)
'smooths' is the second definition.
(I've seen this before)
(Other definitions for irons that I've seen before include "Smooths clothes" , "Imposers of restrictions" , "cuffs" , "instruments of restraint" , "Metal shackles and golf clubs" .)
