Barbershop accessory (5)
I believe the answer is:
strop
'barbershop accessory' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for strop that I've seen before include "Razor-sharpener" , "Strip of leather on which razor is sharpened" , "Razor sharpener" , "Piece of leather on which razor is sharpened" , "rage" .)
