Unsharpened (5)
I believe the answer is:
blunt
'unsharpened' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for blunt that I've seen before include "6 [JOHNSON]" , "Lacking edge; forthright" , "Forthright - Soviet spy" , "Needing sharpening" , "Dull or tactless" .)
