Desire to get rid of power tool (3)
I believe the answer is:
hoe
'tool' is the definition.
(hoe is a kind of tool)
'desire to get rid of power' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is found within the answer.
The remaining letters 'he' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hoe that I've seen before include "Romanians (anag) -- European enclave" , "Purple gem" , "Garden implement" , "Tool; promontory" , "Weed" .)
