Kind of block chopper (9)
I believe the answer is:
battleaxe
'kind' is the definition.
I know nothing about this answer so I can't judge whether this works.
'block chopper' is the wordplay.
'block' becomes 'battle' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'chopper' becomes 'axe' (something which chops).
'battle'+'axe'='BATTLEAXE'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for battleaxe that I've seen before include "Bill" , "domineering wife?" , "Woman we fear" , "aggressive woman" , "Weapon - domineering woman" .)
