Though badly tooled, has produced fine cutlery (6)
I believe the answer is:
toledo
'produced fine cutlery' is the definition.
The definition suggests a singular noun which matches the answer.
'though badly tooled' is the wordplay.
'tooled' anagrams to 'TOLEDO'.
But, I'm not clear how the anagram is indicated.
'has' is the link.
Can you help me to learn more?
(Other definitions for toledo that I've seen before include "Tapering sword" , "City in central Spain famous for swords" , "Spanish city, famous for steel and swords" , "Looted the Spanish city badly" , "Covering, hiding" .)
