Feed king confused point in tense situation (5,4)
I believe the answer is:
knife edge
'tense situation' is the definition.
(I've seen this before)
'feed king confused point' is the wordplay.
'confused' indicates an anagram.
'point' becomes 'E' (compass point).
'feed'+'king'='feedking'
'feedking' anagrammed gives 'knifeedg'.
'knifeedg'+'e'='KNIFE-EDGE'
'in' acts as a link.
(Other definitions for knife edge that I've seen before include "Sharp cutter" , "in precarious position" , "dangerous situation" , "critical situation" , "perilous place on which to be" .)
