Ragged sort of blade (6)
I believe the answer is:
dagger
'blade' is the definition.
(I've seen this in another clue)
'ragged sort' is the wordplay.
'sort' is an anagram indicator.
'ragged' is an anagram of 'DAGGER'.
'of' is the link.
(Other definitions for dagger that I've seen before include "Hand weapon" , "Short knife for stabbing" , "Macbeth's weapon" , "Stabbing weapon" , "Murder weapon" .)
