'a sound clause but potentially damaging' is the definition.
I can't tell whether this definition defines the answer.

'a sound clause' is the wordplay.
'a sound' indicates a 'sounds like' (homophone) clue.
'clause' is a homophone of 'CLAWS'.

Can you help me to learn more?

(Other definitions for claws that I've seen before include "Talons" , "Grasping limbs, of a crustacean, say" , "beastly offensive" .)
