Demonstration of courage that’s shown while shaving? (5,5,3)
I believe the answer is:
stiff upper lip
'demonstration of courage' is the definition.
'stiff upper lip' can be an answer for 'courage' (I have seen 'Calm courage ' mean 'stiff upper lip' so perhaps 'courage' could also mean 'stiff upper lip'). I am unsure of the 'demonstration of' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for stiff upper lip that I've seen before include "Calm fortitude" , "Very British stoicism" , "Doggedness" , "British self-restraint" , "that may be under one's nose" .)
