Barbershop sharpeners (6)
I believe the answer is:
strops
'barbershop sharpeners' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for strops that I've seen before include "Leather razor sharpeners" , "temper tantrums" , "bits of leather" , "Sharpens on piece of leather" , "Leather straps to sharpen razors" .)
