Utensil wasted loot (4)
I believe the answer is:
tool
'utensil' is the definition.
(I've seen this in another clue)
'wasted loot' is the wordplay.
'wasted' indicates anagramming the letters.
'loot' is an anagram of 'TOOL'.
(Other definitions for tool that I've seen before include "Hand implement" , "Person exploited" , "Maybe saw" , "Instrument, implement" , "Practical implement" .)
