It might be used to cut some flipping beef in kitchen (5)
I believe the answer is:
knife
'it might be used to cut' is the definition.
(knives cut things)
'some flipping beef in kitchen' is the wordplay.
'flipping' shows that the letters should be reversed in order.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'efink' is hidden within 'beef in kitchen'.
'efink' back-to-front is 'KNIFE'.
(Other definitions for knife that I've seen before include "Dagger" , "Cutting blade" , "Cutting tool" , "following Stanley perhaps" , "Edge tool" .)
