Trowel used on odd foot part (3)
I believe the answer is:
toe
'foot part' is the definition.
('toe' is part of 'foot')
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for toe that I've seen before include "Lower tip of something" , "Digit; kick" , "low digit" , "Drive obliquely" , "Foot extremity." .)
