It is 7.25 by 1.25'' IIRC. I don't have any copper wire, but I scratched the stone with a 2 pence coin which is plated in copper and left a white scratch. Different story when whetted. The stone removed the copper rather quickly, turning the water dark grey. Not slurry, as the slurry is a white colour.
