Emery

Tom used a piece of emery to smooth the rough edge of the metal.

Before painting, Mary rubbed the surface with emery to remove imperfections.

Tom carried a small strip of emery in his toolkit for quick touch-ups.

It took me from nine to ten days to grind and polish it ready for parabolising and silvering. I did this by hand labour with the aid of emery, but without a lathe. I finally used rouge instead of emery in grinding down the glass, until I could see my face in the mirror quite plain.
