Meat cut with long, loud implement (9)
I believe the answer is:
pitchfork
'implement' is the definition.
(pitchfork is a kind of implement)
'meat cut with long loud' is the wordplay.
'meat' becomes 'pork' (pork is a kind of meat).
'cut with' indicates putting letters inside.
'long' becomes 'itch' (to long or itch for something is to desire it).
'loud' becomes 'f' (short for forte - 'loud' in music).
'itch'+'f'='itchf'
'pork' going around 'itchf' is 'PITCHFORK'.
(Other definitions for pitchfork that I've seen before include "thrust into position" , "Tool for tossing hay" , "multi-pronged tool" , "Implement for tossing hay" , "Thrust into a difficult situation" .)
