Revive and reshape it with secateurs (11)
I believe the answer is:
resuscitate
'revive' is the definition.
(I know that revive can be written as resuscitate)
'reshape it with secateurs' is the wordplay.
'reshape' indicates anagramming the letters (I've seen 'reshaped' mean this).
'with' is a charade indicator (letters next to each other).
'it' put after 'secateurs' is 'secateursit'.
'secateursit' is an anagram of 'RESUSCITATE'.
'and' is the link.
(Other definitions for resuscitate that I've seen before include "Bring back to life" , "Revive" , "Bring round" , "Bring back from unconsciousness" , "Make active again" .)
