Skating manoeuvre exposes brave act in extremely imposing finale of routine (7,4)
I believe the answer is:
outside edge
'skating manoeuvre' is the definition.
(I've seen this before)
'exposes brave act in extremely imposing finale of routine' is the wordplay.
I cannot really see how this works, but
'exposes' could be 'outs' (outing is a kind of exposing) and 'outs' is found in the answer.
'act' could be 'deed' (deed is a kind of act) and 'deed' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for outside edge that I've seen before include "position in ice-skating" , "part of ice-skate" , "One's going to slip, perhaps" , "skating manoeuvre" , "Chance to slip maybe" .)
