Cut share, maybe (5)
I believe the answer is:
shear
'cut' is the definition.
(I know that shear is a more specific form of the action cut)
'share maybe' is the wordplay.
'maybe' indicates an anagram.
'share' anagrammed gives 'SHEAR'.
(Other definitions for shear that I've seen before include "Cutter" , "shave" , "strain" , "Cut wool off (a sheep)" , "Cut sheep's woll with large scissors" .)
