'such a blow shouldn't' is the definition.
I can't tell whether this definition defines the answer.

'damage german school' is the wordplay.
'damage german' becomes 'g' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'school' becomes 'lancing' (I've seen this before).
'g'+'lancing'='GLANCING'

Can you help me to learn more?

(Other definitions for glancing that I've seen before include "Having a quick look" , "Glimpsing" , "blows are like this" , "Briefly looking" , "(Of blow) bouncing off" .)

I've seen this clue in The Sunday Times.
