Hone temper (5)

I believe the answer is:

strop

This clue is a double definition.

'hone' is the first definition.
(I've seen this in another clue)

'temper' is the second definition.
(I've seen this before)

(Other definitions for strop that I've seen before include "rage" , "Leather strap used to sharpen razors" , "Sharpen an old blade" , "Display of temper" , "Outburst" .)

I've seen this clue in The Everyman puzzle in The Observer.
