Slight contact that can break skis (4)
I believe the answer is:
kiss
'slight contact' is the definition.
'kiss' can be an answer for 'contact' (thesaurus). I'm not certain of the 'slight' bit.
'can break skis' is the wordplay.
'skis' can be anagrammed to 'KISS'.
Though, I am not clear how the anagram is indicated.
'that' is the link.
Can you help me to learn more?
(Other definitions for kiss that I've seen before include "Peck (on cheek or lips?)" , "Act of osculation" , "drop of wax" , "Caress with lips" , "Affectionate greeting" .)
