Police officer seizes hard, bladed weapon (7)
I believe the answer is:
chopper
'bladed weapon' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'police officer seizes hard' is the wordplay.
'police officer' becomes 'copper' (copper can informally mean a police officer).
'seizes' is an insertion indicator.
'hard' becomes 'h' (abbreviation used in pencil classifications).
'copper' enclosing 'h' is 'CHOPPER'.
Can you help me to learn more?
(Other definitions for chopper that I've seen before include "Blade" , "An informal helicopter, or an axe" , "Hatchet" , "Lizzie Borden" , "An axe, or a slang helicopter" .)
