Abrasive powder (5)

Ross

I believe the answer is:

emery

'abrasive powder' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for emery that I've seen before include "Hard black-grey mineral used in grinding and polishing" , "Coating on paper used as an abrasive" , "Abrasive form of corundum" , "Abrasive material" , "Hard, grey-black mineral used as 11 down" .)

I've seen this clue in the Universal, the Newsday, the King Feature Syndicate and The Times.
