Notice in quarrels some piercing objects (8)
I believe the answer is:
bradawls
'some piercing objects' is the definition.
(a bradawl is a tool for piercing holes)
'notice in quarrels' is the wordplay.
'notice' becomes 'ad' (both can mean an advertisement).
'in' indicates putting letters inside.
'quarrels' becomes 'brawls' (brawling is a kind of quarreling).
'ad' placed within 'brawls' is 'BRADAWLS'.
(Other definitions for bradawls that I've seen before include "Those boring" , "They bore" .)
