Secured by spike, deadly scrap metal objects (7)
I believe the answer is:
tinware
'metal objects' is the definition.
(items made from tin)
'secured by spike deadly scrap' is the wordplay.
'secured by' indicates putting letters inside (inserted letters are held or secured).
'spike' becomes 'tine' (spike of a fork).
'deadly scrap' becomes 'war' (scrap can mean a fight).
'tine' placed around 'war' is 'TINWARE'.
(Other definitions for tinware that I've seen before include "Metal items" , "Articles made of metal plate - wet rain (anag)" , "Metal products" , "Baking sheets" , "Metal objects" .)
