I detest established imagery: I study nothing about object personifying cobblers (10)
I believe the answer is:
iconoclast
'i detest established imagery' is the definition.
(someone who destroys icons)
'i study nothing about object personifying cobblers' is the wordplay.
'study' becomes 'con' (con can informally mean to study).
'nothing' becomes 'O' (O resembles 0).
'about' becomes 'c' (abbreviation for 'circa').
'object personifying cobblers' becomes 'last' (last can mean a tool used by cobblers).
'i'+'con'+'o'+'c'+'last'='ICONOCLAST'
(Other definitions for iconoclast that I've seen before include "Rebel" , "Debunker of reputations" , "Critic of faith" , "A dissident" , "heretic" .)
