Capture piece — it will secure things more quickly! (4,3)
I believe the answer is:
nail gun
'it will secure things more quickly' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'capture piece' is the wordplay.
'capture' becomes 'nail' (I've seen this in another clue).
'piece' becomes 'gun' (slang term for a gun).
'nail'+'gun'='NAIL-GUN'
Can you help me to learn more?
(Other definitions for nail gun that I've seen before include "Fixing tool" , "In a lung (anag.)" , "Woodworking tool" .)
