Those razor-sharp Sheffielders? (6)
I believe the answer is:
blades
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for blades that I've seen before include "Metal runners on skates" , "Cutting parts of knives" , "Leaves of grass or cutting tools" , "Knife edges or dashing fellows" , "cutters" .)
