Stick with revised point showing common sense (8)
I believe the answer is:
gumption
'common sense' is the definition.
('gumption' can be a synonym of 'common sense')
'stick with revised point' is the wordplay.
'stick' becomes 'gum' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'revised' indicates an anagram.
'point' with letters rearranged gives 'ption'.
'gum'+'ption'='GUMPTION'
'showing' acts as a link.
(Other definitions for gumption that I've seen before include "Courage needed!" , "Informal drive and initiative" , "Nous" , "Fortitude and determination" , "To impugn (anag) - common sense" .)
