An old copper kitchen tool (6)

I believe the answer is:

peeler

I believe this is a double definition.

'an old copper' is the first definition.
(I've seen this before)

'kitchen tool' is the second definition.
(I've seen this in another clue)

(Other definitions for peeler that I've seen before include "Old policeman (useful for potatoes!)" , "Old London policeman" , "apprehended by a _____?" , "Very old English cop, or spud scraper" , "Devious type" .)

I've seen this clue in the Evening Standard.
