Butcher came with the broad-bladed knife (7)
I believe the answer is:
machete
'broad-bladed knife' is the definition.
(type of knife)
'butcher came with the' is the wordplay.
'butcher' indicates an anagram.
'with' says to put letters next to each other.
'came'+'the'='camethe'
'camethe' anagrammed gives 'MACHETE'.
(Other definitions for machete that I've seen before include "The mace (anag.)" , "Broad heavy knife used in S America" , "Knife for hacking" , "Broad heavy knife used in S American jungles" , "Cheat me over broad heavy knife used in jungle" .)
