Used a peeler (5)
I believe the answer is:
pared
'used a peeler' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pared that I've seen before include "Trimmed - peeled" , "Did prune" , "Whittled as with pencil" , "Of a fruit, peeled" , "Trimmed like pencil." .)
